Slightly different experience here. The latest XF68_FBDev in XFree 3.3 
was usable with the 2.2 kernels (mostly from BenH's tree), though the
refreshing problems and vertical lines becoming slanted were certainly

Which one is that? I've installed Ani Joshi's latest driver from 
penguinppc.org, and that only crashes the machine when I've booted with
BootX (right on starting up X, in fact).
When booted with yaboot, XF4 has a habit of spontaneously dying after
1 sec--10 min, but never harms the OS. Refresh and display is excellent
however, as long as it's up ;^/.
Maybe I should give 2.4 a fresh attempt, though it might be that some of
the fb drivers in Ben's tree are in fact backported.

Yep, and it's the only thing I can use now I have XF4 installed. After
a while I also see some slanted lines, but much less than with XF3.3 FBDev.
Xpmac(rev.10) also has the strange effect of messing up my console when
I'm using the SUN12x22 console fonts and booting with yaboot. Switching 
to a 16 pixel font fixed that for the moment.
