qemu and l4linux2.4

There is a bug in the current interrupt handler code.  I'm not 100% sure
but I think we have a patch to that.  The problem is that with Pistachio
we run APIC interrupt mode and when IRQs are disabled they usually get
re-injected with a self-IPI (I'm not arguing about the sensibility of
that strategy though).  Right now L4Linux doesn't do that and the IRQ
gets lost.
