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.
