Yeah.. it's a bit difficult atm. 

Also many of the consumer motherboards seem to have buggy BIOSes regarding VT-d 
support.. 
so even if your motherboard has VT-d support, it doesn't mean it actually works 
:)

Asus is known to have multiple motherboard models with broken BIOS.. 
(they have wrong memory ranges in the VT-d DMAR tables).

When you get a new motherboard make sure to browse through xen-users and/or 
xen-devel 
archives and see what motherboards people have been successfully using..
