I don't think that's right either...  register 6B is an IDE interrupt
routing register, not the interrupt itself.

If the iosapic system is supposed to remap the register, I don't think
it is and I don't know where this is supposed to happen.  I hope we can
do all of this using just a PCI quirk.

I've committed it, and it definitely does not work, but I don't think
it'll break anything either.  This is mostly mkp's code.
