2.6.12-rc5-git8 regression on PPC64

[Roland Dreier]

I'm seeing something possibly related as well -- with an up-to-date
git tree (HEAD == d8d088d25822b0199fdfb392085e1cf8a5914a97), I get a
hang early in the boot on an OpenPower 710 (2 x POWER5).  It seems to
get just a little further:

and that's the last thing I see.
