I'm interested in knowing why the machine isn't booting some kernels,
but will happily boot another. I figure if it's a hardware issue, then
it should be an all-or-nothing issue? I'm positive this is the same
spec as the last servers built for this same purpose, but the others
are now on the other side of the country, so I can't access them to
verify.

So assuming the hardware is exactly the same, and assuming there's
something in the -164 kernel that doesn't like that particular fake
raid card, then I still can't see why I can't boot the -128 kernel as
that's what the other boxes have running. :/
