Offb is always unaccelerated. It's more or less a similar thing to the old
cyberfb that can't set video modes: it just uses the frame buffer given by Open
Firmware.

Hmm, 2.2.10 (from http://cvs.on.openprojects.net/) works fine with atyfb on the
Powerbook G3 of my server, which also has a RageLTPro. And XF68_FBDev is
accelerated.
The question is: why doesn't like atyfb the chip?
