Are you sure you built the module against the correct xen config''ed
kernel? (If you''re using a version of xen prior to 3.0.2 you''d
need to
set ARCH=xen on the make command line).

I''m building against the dom0 kernel.  In fact, I copied my module code
into the kernel itself and added an option for it to the Kconfig.  Still 
had the same problem.  It''s very odd, because many other places in the 
kernel use those calls, with no issues...  Maybe it''s just some quirk 
with my configuration.
