One possibility is that the driver is depending on contiguous physical 
memory, and domain0 usually happens to get that (but domUs generally 
will get fragmented physical memory). You could confirm this by making 
a debug build of Xen (debug=y make) which deliberately jumbles the 
physical memory map for domain0. It's quite possible that this will 
then cause the driver to fail on dom0 too. If we can diagnose that this 
is the problem, it probably won't take much to fix the driver.
