5.0_BETA display problem on PPC Mac Mini

[Urban Boquist <urban%boquist.net@localhost>]

Hi all, I tried a 5.0_BETA GENERIC kernel on my G4 Mac Mini and it
_almost_ works - the only problem is that the display goes black as
soon as it starts to boot. But except for that it starts OK and can be
reached from the network, but the console is useless.

I think it is the same problem that Krister Walfridsson reported:

http://mail-index.netbsd.org/port-macppc/2008/03/thread1.html#000331

If I remove radeonfb from the kernel it uses genfb instead and the
display works just fine. The 4.0 kernel uses ofb which also works fine.

This is not a big problem for me, I use this machine headless so genfb
is good enough. But if someone wants to debug this I can at least help
and run some tests.

Best regards,
