I'm certain they do.  One minor motivation for leaving the old board, 
the nightshade chipset is much more advanced than the consumer grade
chipset on the old board.

Hmmm.  Hadn't thought of that.  I never heard that kernels built on one
machine would have chipset dependencies.  Ok, I'll throw an IDE drive in
the nightshade, and see if I can get through an RH install and kernel
build.

Most of the devices are in external cabinets which have their own (dual)
power supplies.  There are only four drives in the chassis itself (two
pair of 4.5gb fujitsus),  and it currently runs with the really huge
~300W ps in the ancient AT case.

I'll try that if the kernel build doesn't work.
