Really?

Ah, so it is... yes, making this architecture dependant might be a good idea. Large PPC and MIPS boxen need to adjust this already. Also, someone did a starfire port, I think that had 64 processors, not sure.
You can. But you cannot buy 32-processor PII (-Xeon) systems that are supported by Linux.
What is the limit here? The 8/16 way SE chipsets?

Oh, then they definately need to send me one.
Are these not MP1.4 based? Something different?
