panic on pccard insert

[Pawel Worach]

Whatever pccard i insert, here an unsupported 3Com OfficeConnect
WiFi card or even a Intel Pro/100+ Mobile16 card it panics like
seen below. This happens if booted with the card inserted and
if hotplugged. The laptop is booted "diskless" so I can't produce
a crashdump (the info below is typed by hand).
