I do see a similar issue with a Tyan s2885 (Thunder K8W) motherboard,
where the 2nd root bus isn't detected with ACPI kernels.
The problem is that the DSDT is missing the PCI Routing Table (_PRT)
for this bus, which is AFAIK mandatory.
I asked Tyan to fix the BIOS; but unfortunately, as my motherboard is
EOLed, they said that they won't correct it :-(
