I have been largely ignoring this thread, because it seems like the
signal/noise ratio dropped pretty quickly, but... If this is for the
VIA chipset problem, this really is pretty easy...
We should promote the "bus" number into the pci_attach_args(), and then
pcibtab = pci_make_tag(pa->pa_pc, pa->pa_bus, pa->pa_device,
0 /* function of the ISA bridge */);
...and then read config space to your heart's content.
