I'd like to pass a pci-device to a winXP-domU. AFAIK VT-d is 
necessary for that.

I did have a lot of IRQ-problems passing a Fritz!Card PCI for vbox3 
and isdnlog to a domU running xen-sources-2.6.31-r10. Downgrading to 
2.6.18-r12 I finally got it working with fcpci yesterday.

If I cant't get the pci-card to work with the winXP-domU I'll try the 
USB-Version of that card. If I understood that correctly, USB 
passthrough should work without VT-d.
Thanks for your answer,
Christian
