Note that it didn't work for me the first time round.  I had to specify
only 'video=aty128fb' without any more arguments for it to work.  For some
reason if I specify the res & bit depth my monitor goes black when
starting X.  OTOH I'm not exactly using a DV either, mine is a Blueberry
iMac 350, should be similar.  Using yaboot of course.

Okay, I got it to (mostly) work. The culprits seemed to be
CONFIG_FB_COMPAT_XPMAC; removing that option from my kernel config allowed
me to properly switch to all color depths. The fb console has several
weird effects when switching vts (displaying garbage briefly during the
switch; cursor changing color), but Xfree 4.0 runs perfectly.

Only other problem is that the geometry is off. The picture is shifted a
couple pixels offscreen to the left in 16-bit mode, and even farther in
32-bit. But this is definitely a big step forward.

[I'm on a blueberry 350 iMac as well.]

Simply adding the XPMAC compat. option should not harm... I'll looks if I
see a bug related to it.

For the geometry problem, I beleive the modelines used by Apple for the
iMac are a bit different than the ones in the standard base we use. You
should be able to adjust your XFree modelines.
