I needed the patch below when I tried the xen-unstable version
yesterday. I don't see how it can be related to the problem you are
seeing but with it they work fine for me on RHEL4 and SLES9. I didn't
try 2.6.16 but I will on Monday.

Are you sure you are building against the correct kernel headers for the
kernel you are running?
