Courtesy of a friend (and customer) in Melbourne I've been given sight 
of their /proc/cpuinfo info and they show precisely the opposite from  
what I've seen with our Intel and AMD boxes. :-)

Their systems are HP and show that their AMD systems enumerate the 
first core on each socket first, then the second, etc, whilst their 
Intel boxes enumerate all the cores on one socket before doing all 
the cores on the next socket.  This is the same for both their dual 
and quad socket boxes.

Their RHEL3 boxes (2.4.21-32.ELsmp) show physical id's & siblings for 
the single core (with HT) boxes but not core ID's, so here we can't 
tell a dual core Intel from an HT Intel system. :-(

Ah - of course we don't care here because it won't have cpusets 
support! :-)

cheers,
Chris
