If you're trying to use 4.0-RELEASE, you'll probably need at least
the following patch to handle the two IOAPICs. If the 7000 has the
same RCC chipset as the 5600, you may also need a separate patch to
recognize this chipset and handle all the PCI buses.

My fault, I made a mistake in the patch. Here's the correct one
(the offset should be added before typecasting),
