Good luck there :)

Hmm... I don't use kernel-modules in my Xen domu's (All are PV). I wonder
if compiling them into the kernel might help.
Or, try loading the modules listed above and see if that helps. (Not sure
if you can see an immediate change though)

I have attached the .config for one of my domains. It also has support for
a passed-through sound-card. You won't need that part. :)

Please note, I do use the following kernel:
sys-kernel/xen-sources-2.6.34-r4

Which kernel are you using?

That's always a good way to make people more happy to help :)
