Someone mentioned that the SBC card model might be more helpful than that
of the passive backplane. All I was able to find about it was "PSC-586".

A couple people also mentioned that they remember a patch for something
similar (although perhaps not the same) a while back. I searched the
archives and came up with nothing. Any better ways to search for it?

Someone else suggested it might be useful to look at the model numbers on
the chips on the SBC. Here they are:

VIA
VT82C42N
9512CF
(VIA's website lists VT82C42 as a keyboard/mouse controller chip)

ALI
M1449 A3
9445 TS2
B27925

ALI
M1451 B1
9450 TS2
AB1831

SMC
FDC37C665GT
B9525-D3470AIC
6H75 865-3

BENCHMARQ
bq3287MT
9525SB2
PM525016
(website looks like they make CMOS stuff)

Output from booting with -v set:

Wait a sec! It detected my ethernet card there!

After a lot more investigation, I've found that (with a fully installed
system) if I cold start the machine, it won't detect the PCI bus (it won't
even detect any chips). However, if I restart the machine, it'll detect it
on the next bootup.

HOWEVER even though it detects the PCI cards they don't appear to work. I
tried both the 3Com card and an fxp0 card, both which I know work. I could
ifconfig both, but whenever I tried to ping anything over the network
nothing would come back (but it will under linux). With the fxp card, the
kernel would report fxp0: device timed out

So maybe it can kinda see the PCI stuff, but it's not communicating
properly with it? I don't know. :/
