I will try a few installs on my Q9550 with:

Win XP SP2
Win Vista
Win 2k8 HPC


All with 4 CPUs enabled and post the results.
But i have the assumption that the qemu-cpus are recognized as physical 
sockets by windows xp hence only two are available.
Will post back when i have results - or either of the Daniels would have 
an answer - but i think it is more a linux-kvm or qemu thing.
