PCIE port bus driver depends on PCI_GOMMCONFIG to locate service
attributes
for advanced error reporting (AER) and virtual channel (VC) for each
PCIE port.
Without PCI_GOMMCONFIG, then a read to 0x100 offset or above will return
0xffff;
in other words, neither AER nor VC service support is found. We would
like to move
forward to have PCI_GOMMCONFIG dependency as the new features come
along. RHEL 4
is shipping with PCI_GOMMCONFIG configured into the kernel by default
and we 
expect the next major version of SuSE linux to do the same.

Thanks,
Long
