A few notes of caution...

864s and 964s/968s are distingusihed by whether they have DRAM or 
VRAM interfaces respectively. These chips need to be programmed 
differently, on account of their memory interfaces are wildly 
different, if you want anything other than 640x480x1. Or put another 
way, any settings based on 864s will be very disappointing.

Thus if a Spea Mirage has an 864 on it, mods for it won't drive a 
968.

SuperProbe will only tell you what chips you have, not whether 
aux/vga will work!

vgadoc3 is getting a bit long in the tooth these days.

XFree is the most complete (complex?) source of vga programming, but 
I needed the S3 data books to understand what it was doing. Let's say 
the code is not self-documenting.
