HT is an odd beast. Running top, it shows two cpus, total bogomips is like 
11000, but hardly a speedboat by anymeans. Running 2.6.14.x kernel with smp 
and ht turned on and well... not real impressive. For the mix of apps I run, 
it's far smoother when running smp turned off. 

Another side note, I've been all over the net, looking for smp aware audio 
drivers for atiix and there are none. So, no audio when tinkeering with 
smp...

That aside, I'm taking the pickup down to the local liquor store... anybody 
need anything? :')
