I know your PowerBook was affected by the problem fixed by commit
b7d8cce5b558e0c0aa6898c9865356481598b46d ('drm/radeon/kms: MC vram map

Dave ? Was this ever merged ?
Apparently it went into 2.6.37, I didn't notice because it went into
different places in the code compared to the patch I had from you.
* Various endianness issues in the Mesa drivers.
Right, and the later aren't getting any better :-( It's busted even
without KMS nowadays.
Unfortunately, I have about 0 time to spend on that at the moment.
I recommend that distros stick to radeonfb + UMS for the time being on
ppc32.
One problem being that the classic Mesa r300 driver is essentially
unmaintained, and evidently rotting

I've now talked briefly to the DRI and powerpc upstream maintainers, and
the answer is that radeon is mostly broken on at least 32-bit powerpc
while nouveau is in better shape but not quite stable yet. So I'm going
to revert most of the FB configuration changes I made in 2.6.37-1 for
the next upload to unstable.

rebooted into 2.6.37-2-powerpc which did not complete the booting
procces just the way 2.6.37-1-powerpc did.
This also works on a PowerBook G4 here. Presumably, without this
vga16fb tries to take over from offb, and this does not work. I didn't
imagine that it would try to do that!
* Has anyone tested 2.6.37-{1,2} on a non-Mac system yet, and does

Using this parameter, I can get as far as running some of the init
scripts, but as soon as the radeon driver (*not* radeonfb) is loaded -
either by udev or the X server, depending on modprobe configuration -
the screen goes black - handover from offb to radeon is not working.
I also tested 2.6.38-rc6-1~experimental.1. Here, the radeon driver
prints a few lines, ending with:
fb: conflicting fb hw usage radeondrmfrb vs OFfb ATY,Xia_A - removing
generic driver
and then nothing more is displayed on the screen (though the system is
otherwise alive). So it seems that radeon is not yet able to take over
from offb and we need to stay with radeonfb and UMS in X for now.
* Could some Mac users test and report whether i915 or nouveau can
successfully take over the display from offb in 2.6.37 or 2.6.38-rc6?
