the number of registered adapters instead of determining again whether stdout is a supported card (and which might have failed to attach and register). - Drop creator_set_mode() and move the relevant parts to creator_fill_rect() and creator_putc() respectively. This is a bit cleaner than having to make sure that creator_set_mode() was called before creator_fill_rect() or creator_putc() are used and matches better what Xorg does. - Fix a bug in the handling of the FBIOSCURSOR IOCTL; the code was meant to return ENODEV for all invocations expect when used to disable the cursor and not just when used for enabling the cursor. - In case the adapter is the OFW stdout move its OFW cursor to the start of the last line on halt so OFW output doesn't get intermixed with what FreeBSD left on the screen. With hindsight this is what the faking of a hardware cursor which was removed in the last revision really was about, i.e. to keep the OFW updated about the current cursor position. The new approach however is simpler while producing the same result and doesn't cause the first letter of the OFW output to be turned into a blank and a newline. - Add variable names to the prototypes of creator_cursor_*() which were added in the last revision and list them alphabetically in order to match the style of this file.
