Still using Xpmac.rev10. Should I try XFree86 again? What about a newer
kernel and/or XFree86 4.0? Whoa! Living on the bleeding edge, lol. Hey
Moonglue, not hearing anything from ya. <g>

With No Video Driver box checked;

        MacOS display is /bandit/ATY,Rage128o
        Using unsupported 1024x768 ATY,Rage128o at 96008000, depth=32,
        fb0: Open Firmware frame buffer device on /bandit/ATY,Rage128o

Question: I think I read somewhere that checking the box diables
acceleration or something. True or false?

Close. I have

        L2CR overriden (0xa9100000), backside cache is enabled

>Of course, BootX must be configured to turn backside cache on.

Yep, it's checked.
