Binary modules in general won't be compatible between Xen and non-Xen 
kernels...  They may not load, and even if you did load them they may not 
work because of the differences between Xen and bare metal.

People have managed to load the binary blobs for graphics drivers but fiddling 
with the wrapper code, though.

Summary: to be more sure it'll work, it's better to compile the module for the 
Xenified kernel.
