to vga_pci.c to request on behalf of it's children. This causes vgapci to show
up as the interrupt owner in vmstat -i, rather than the child device.

capability is present as not all devices supported by the agp_i810 driver
(such as i915) have the AGP capability. Instead, add an identify routine
to the agp_i810 driver that uses the PCI ID to determine if it should
create an agp child device.
as a bus so that other drivers such as drm(4), acpi_video(4), and agp(4)
can attach to it thus allowing multiple drivers for the same device. It
also removes the need for the drmsub hack for the i8[13]0/i915 drm and agp
drivers.
- Move PCI core code to dev/pci.
- Split bridge code out into separate modules.
- Remove the descriptive strings from the bridge drivers. If you
want to know what a device is, use pciconf. Add support for
broadly identifying devices based on class/subclass, and for
parsing a preloaded device identification database so that if
you want to waste the memory, you can identify *anything* we know
about.
- Remove machine-dependant code from the core PCI code. APIC interrupt
mapping is performed by shadowing the intline register in machine-
dependant code.
- Bring interrupt routing support to the Alpha
(although many platforms don't yet support routing or mapping
interrupts entirely correctly). This resulted in spamming
<sys/bus.h> into more places than it really should have gone.
- Put sys/dev on the kernel/modules include path. This avoids
having to change *all* the pci*.h includes.
