Done. The dmesg output is appended. Just send me a gift certificate
for Tim Horton's or something like that.

What you see is,

    bus device function	
    0	0	0	PCI/memory controller
    0	1	0	PCI-to-ISA bridge
    0	1	1	IDE interface
    0	9	0	ATI Mach32 Graphics card
    0	11	0	Adaptec 2940 SCSI controller
    0	13	0	PCI 4-port tulip card (bridge, with 4 21040s behind it)

So there are only two PCI buses on the dmesg output, and one of
those is on my quad-tulip card.
