fglrx is the ATI binary only/proprietary driver? I think that's your
problem. ATI are the only ones who can fix that to work with Xen.

The open source radeon driver does work just fine for me on 2.6.32 and
has done for some time. I don't believe the required fixes are in 2.6.37
though, although they might be queued for 2.6.38.
