As it turns out, it appears that the panic is caused by disabling the
PnP BIOS.  There are at least two chips (same `device' using IRQ 10 and
under FreeBSD, their use is reported as int "a" and "b" for irq 10).
They appear to be the CardBus bridge chips (1013,1110 rev 0xc1) under
FreeBSD.

Alas, even with PnP BIOS enabled, it's of questionable use - NetBSD 1.4
freezes if either of my PCMCIA cards are inserted at any stage whilst it
is running :-(

If anyone wants to test some changes, please let me know...I'll try anything
to get a non-MS OS running with networking that isn't linux!
