I know it would be slow...be couldn't you use VESA mode for this? As long
you have a monitor for this...VESA would be acceptable (maybe 10-30%
slower). If you implement LFB (VESA 2) for it, that would be cool too.
If you dont know where to start this, try looking at the Allegro &
FreeBE/AF sources. S3 support is in there. Try these links...
