This is only temporary. Our real goal is to have full featured drivers that can initialize the chipsets theirselves. All help is welcome, of course.
BTW, cyberfb.c (S3 Trio64) was recently enhanced for this. Currently not yet in Linus tree though. But it's in the m68k tree. Ideally it should be merged with S3Triofb.c too.

320x200x8 is doable, but 640x480x4 requires bank switching since the screen image is >64 KB. Thus it would need special fbcon-* low level routines, and no X.
