this is weird. I'm beginning to worry about vmware. I had a printk on this
ffs() stuff in vmware and for ffs(1) I got a zero; on my laptop it just
got 1.

damn.

Also, I fixed another problem in hypervisor_callback by removing
PUSHW ES (push %es for linux folks).

Yep, if the callback pushed ES it would trap, otherwise not. 

arg. I really need to get off vmware soon :-)
