I expected to see two processors.. any ideas?
    

the kernel depends on the bios to enumerate the cpus in order to find
them; if only 1 is found I'd suggest trying to find a bios upgrade; my
HT box needed one to find the second cpu.
  
Tried that - no luck.  Odd thing is that XP sees both of them, though I'm not sure what mechanism it uses to enumerate the processors.   No options in the BIOS other than HT enabled/disabled.

Motherboard is an ASUS P4G8X, btw.
