I like this LAPIC change a lot. Actually I like APICs a lot. They may not
give you 'real' vectored hardware interrupts a la SPARC and PowerPC, but
at least it comes a bit closer.

It would be nice to be doing APIC on uniprocessor systems a bit further
down the line, but that's for the wishlist -- the 8259s are not going away
just yet.
