That wasn't the subarch cleanups that removed it, please be careful
what you're saying. I plead not guilty to that one.

Additional PCI-PCI bridges (eg starfire cards) have never been supported 
in non-boot quads. It's not impossible, but don't be suprised if it 
doesn't work.

You don't have PIT support compiled in, and you turned off TSC support,
leaving yourself with no timer. There's a patch in my tree to force on
PIT support for NUMA-Q.
