Yes, I discovered the most wonderfully ugly hack of all time. Find a 
random kernel function, get a pointer to it, subtract the offset (as 
found in the xMAP) to get the relocation offset, and add the offset of 
the function you want to call. Cast to the appropriate function type, 
and call by pointer. Incredibly ugly, but it works.
