Recent changes upstream are breaking fbdev on pmacs.

From what I see, it seems that offb is kicking in by default, reserves
the mmio regions, and then whatever chip driver loads can't access
them.

offb is supposed to be a "fallback" driver in case no fbdev is taking
over, it should also be "forced" in with video=ofonly kernel command
line. This logic has been broken.

I *hope* this is what I'm seeing with recent kernels, though I
have my doubts....  What I *do* know is that with recent bk snapshots
(post bk-1.2115) I have the following:  radeonfb seems to load, but when I
try to load X, my y-resolution seems to be half of what it ought to be...

X-fbdev, or X + native radeon driver?  Do still get a framebuffer console?
Any other fb apps you have that's also broken?

Hold my tongue: BenH's latest patch (already in mainline) fixes it for me.
