It certainly doesn't work at all without it. It is definetly not
managing to figure out that the generated interupt is for itself.

This looks like it should accomplish the same thing (assuming not bits
get set in status on the initial attempt to read it), without affecting
other platforms and possible the alpha if anyone has a card that just
