Considering how bad OF can be on some machines, I'd like this to be
boot-tested on a wider range of machines. Also, it might depend on the
OF real-base setting as well...
At least, we should be able to test at ozlabs on cell blades, POWER4
bare metal (ie "SMP mode"), POWER5 and POWER5+.
Cheers,
Ben.
