I've taken the machine back to the shop - The MediaGX cpu (which I
previously knew nothing about) scared me... the lengths people go to
so that they can produce something a few $$$s cheaper...
I've replaced it with a machine w/ an Intel chip (FOOF & all).
Interestingly enough, the PCIC probes as a VLSI 82C146 on this
machine too, and my 3c589c seems to be misbehaving in the same
way (IRQs don't seem to work) - but I can see psm0, so it just
seems to be an interrupt thing.
Of course I'm still on 2.2.6-release (no timers mentioned at boot
time, and no sig 24s). I'll try to cvsup to -current from my other
machine over a ppp link if I can't get the NIC to respond tonight.
