The padding isn't the problem; the problem is that Xen is expecting an 
address in there, but it's getting "garbage + {0,1}".  As Jan pointed 
out, how is Xen supposed to distinguish an address from garbage + 
incorrect parameter?
At any rate, I have a patch to the debian kernel I'll post in a bit.
