I have an opteron with 6gig ram running X86-32 with Xen compiled with
PAE enabled. When I do the following to try to ballon down (as xm
ballooning is busted) I get the following:

My guess would be that its overflow in the size calculation. You might
want to sprinkle a few u64 's in the balloon /proc code.
