Maybe check first if the problem still exists in xen 3.0.1

Can't, I am dependent on PCI passthrough. I'm hoping 2.0 isn't abandoned yet..

2.0 is only receiving simple bug fixes. This one would be painful 
enough to fix that we're unlikely to bother, unless we are sent a 
patch. I think it would break the 2.0 I/O interfaces anyway, as the 8+8 
major/minor split is baked into the control interfaces.

PCI passthrough will be in 3.0 series within a week or two.
