I tried it on the weekend. I can report some degree of success.
First I upgraded the machine (ASUS P4P800 MB) to the latest BIOS
(1016). This didn't help. Then I upgraded it from 1.6ZL to 2.0E
(20040509) which didn't help. Finally, I applied your patch. That
worked. The machine is now happily running with two "CPUs"
However, USB isn't functional with a multiprocessor kernel. I
have no idea if this is related to the MPAPCI stuff though. When I
plug in a USB device, it complains that there is a problem and it shuts
down the port. If I boot a non-multiprocessor GENERIC kernel, the
device works fine.
Also, I see some rather interesting output from 'ps auwwx':
