Sort of, yes you can get Quad P4 Xeons, but the Cpus them self only
support 2-way Smp.  Anything above that and you have to use chipsets to
glue the Cpu's together... hardly what I would call feature of the Cpu.
Reminds me of a quad 486 I once saw, afaik the 486 didn't support smp at
all. But the PIII Xeons could do 4-way Smp(just like the Ppro).
