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:

It should have been assigned to the pci subsystem, then it would not be
languishing :)
I've fixed that.
We have a patch in the latest -mm that should take care of this issue.
thanks,
