Most PCI specific files moved from sys/i386/pci to sys/pci.
One PC specific file (pcibus.c) new in sys/i386/isa.
Now it matches the man page and also the only other commercial implementation
i have found so far ( Solaris 2.x).
Changed the name from ss_base to ss_sp.
Display update method changed, now allways write in memory buffer,
then periodically update physical display.
Speed improvements (now > 5 times faster than the old syscons).
History now circular buffer, with changeable size.
History scroll by up/down line, up/down page, home and end.
Backtab proberly implemented.
Now space for 96 function keys, 63 allocated standard, default now
SCO/SYSV compat again as in the old days.
New keyboard definition files ~share/syscons/keymaps/*
Misc fixes for old "hacks" that broke SCO/SYSV compat.
More that I forgot before writing this...
Handles at least Trantor T130 and ProAudioSpectrum adapters.
The pas driver has consequently been removed.
This driver can be configured without without interrupts.
Manpage to follow when PAS16 has been edited in.

case, software cursor now optional case. Driver must provide
raw things (what hardware do for us, exactly) as default case,
all driver features must be _optional_. Modern VGAs have internal
configuration utilities to set cursor shape/blinking which stored
into cards ROM, and syscons nuke out such features completely
by forcing software cursor. Moreover, software cursor is hard
to distinguish on standouted (or near standouted) fields and
tends to disappearse from the screen.
Set "flags 0x4" to enable software cursor now.
o Cleanup screen savers.
o Don't draw cursor if saver or blinker is active.
o Duplicated code moved to functons.
o Add more checks for blinker in progress, character lost otherwise
when blinker restore old contents.
o Reduce blinking counter to 3, too slow in old variant.
o Fix timeout code in scrn_timer(), old variant can reenter iself,
if action takes too long time.
o Disable visual bell for scroll lock mode, saved screen
becomes overwritted otherwise.
(Boot with the -D flag if you want symbols.)
Make it easier to extend `struct bootinfo' without losing either forwards
or backwards compatibility.
ddb_aout.c:
Get the symbol table from wherever the loader put it.
Nuke db_symtab[SYMTAB_SPACE].
boot.c:
Enable loading of symbols. Align them on a page boundary. Add printfs
about the symbol table sizes.
Pass the memory sizes to the kernel.
Fix initialization of `unit' (it got moved out of the loop).
Fix adding the bss size (it got moved inside an ifdef).
Initialize serial port when RB_SERIAL is toggled on.
Fix comments.
Clean up formatting of recently added code.
io.c:
Clean up formatting of recently added code.
netboot/main.c, machdep.c, wd.c:
Change names of bootinfo fields.
LINT:
Nuke SYMTAB_SPACE.
Fix comment about DODUMP.
Makefile.i386:
Nuke use of dbsym.
Exclude gcc symbols from kernel unless compiling with -g.
Remove unused macro.
Fix comments and formatting.
genassym.c:
Generate defines for some new bootinfo fields. Change names of old ones.
locore.s:
Copy only the valid part of the `struct bootinfo' passed by the loader.
Reserve space for symbol table, if any.
machdep.c:
Check the memory sizes passed by the loader, if any. Don't use them yet.
bootinfo.h:
Add a size field so that we can resolve some mismatches between the loader
bootinfo and the kernel boot info. The version number is not so good for
this because of historical botches and because it's harder to maintain.
Add memory size and symbol table fields. Change the names of everything.
Hacks to save a few bytes:
asm.S, boot.c, boot2.S:
Replace `ouraddr' by `(BOOTSEG << 4)'.
boot.c:
Don't statically initialize `loadflags' to 0. Disable the "REDUNDANT"
code that skips the BIOS variables. Eliminate `total'. Combine some
more printfs.
boot.h, disk.c, io.c, table.c:
Move all statically initialzed data to table.c.
io.c:
Don't put the A20 gate bits in a variable.
in the PCnet/Lance family.
Fix attach so 32 bit cards don't call isa_dmacascade.
Add a workaround for 32 bit chips which incorrectly truncate the
ring buffer size.
Fix a bug where CRC errors were reported as framming errors.
Change copyright to a BSD style one.
Moved various pmap 'bit' test/set functions back into real functions; gcc
generates better code at the expense of more of it. (pmap.c)
Fixed a deadlock problem with pv entry allocations (pmap.c)
Added a new, optional function 'pmap_prefault' that does clustered page
table preloading (pmap.c)
Changed the way that page tables are held onto (trap.c).

page flipping anytime soon and 4k just wastes memory. Performance via the
looback interface will decrease slightly by this change. Idealy, we need
buffers that can have variable sizes, but this requires a rewrite of far
too much code at the moment.
