I haven't looked at the X386 for the past couple of years, but at the time
I wanted to add in support for my ATI VGA Wonder card (it's one of the old
V3 type).
I ordered the documentation for ATI, only to find out that in V3 you can't
define different read and write addresses when you access pixels. Therefore,
you cannot blit from one place to the next: you need to read into RAM and
then copy back into the video card at the new location. This is a pain to
do, and the preliminary X386 ATI support I had seen a couple of years ago
very wisely (?!) avoided touching that.
I assumed that this is what is meant in the comments by "V3 board support
needs a lot of work".
The point is a bit moot for me anyway, since my Unix machine only has 4MB
of memory and X wouldn't run well with that little memory (the NT machine
has 16 MB, but that's another story).
Good luck, and let me know if you find anything...
