Ok, have to check out what's in darwin, there are some bits for the
Shasta chipset that I haven't adapted yet.

Ok, weird. Will check that when I get it. Does X "nv" driver work when
booting with offb ?

There have been various USB related issue in 2.6.10-rc*, have you tried
the latest bk ?

I very much doubt it has anything to do with CPU context
saving/restoring... Could be lots of different things, difficult to say
at this point. Thermal problem ? Clock chip setup problem ? Bad
RAMs ? ...
