I'm not questioning whether it works on SGI, what I'm asking is
whether it will work on _all_ possible NUMA architectures, or just on
SN2.

What I worry about is that some distributions may end up shipping
GENERIC kernels, with no easy way to build an optimized kernel.  It's
reasonable to expect highend customers to build their own kernels, but
I don't think that's quite as reasonable to expect the same from
someone who buys a workstation.
