MMCONFIG broken on Tyan K8WE [was: Fusion MPT driver does not detect controller]

This 2.6.15.4 bug is languishing in bugzilla:

http://bugzilla.kernel.org/show_bug.cgi?id=6060

Devices behind a PCI-X bridge are invisible unless the submitter
uses "pci=nommconf". The devices worked in 2.6.13.5, because we
always disabled mmconfig for AMD CPUs then. But now it's broken.

I also found this problem report, which may be the same problem:
