Luckily the r128 driver in XFree 4.0 knows about this card and it is not significantly different from the Rage128 RE card I have in my B+W G3. I think the whole thing comes down to the default timing info being okay for Rage128RE but not okay for RAGE128PF > > I looked in aty128fb.c in the kernel and they hav hardwired defaults which I > can easily change but I need to know about timing info that Mac OS uses. > > Do you know of any probe code or anything at all that can determine timing info > from the MacOS side of things. I will keep looking. I am going to add this card to the Xpmac source so that it tries to use its acceleration code simply on the straight OF frame buffer. If that works, then I should be able to use Xpmac to get some of timing info.
