Actually, I think there _are_ some low-end, single-core "Montecito" processors. 
  Or at least, one can order an rx2660 with a 1.6 GHz single-core CPU.  I'm 
ass-u-me-ing it is a single-core Itanium2 9000 series (aka Montecito).  Click on 
"Options and Accessories" on the page to which http://www.hp.com/go/rx2660 takes 
you.

Hyperthreading should be disabled by default.  To check or reset it one can use 
the cpuconfig command from EFI.
