Yes, I've tried precisely that. Resetting the card through
cardctl eject and cardctl insert and cardctl reset does nothing. Ditto
with popping out the card. Though I haven't had the opportunity to test
this under a more controlled environment, which I'll probably do later
today.

Right. I intend to. I'm not convinced this is a pcmcia problem,
it seems more like an apm problem where some data areas are not being
properly restored after the suspend (this is, of course, assuming I under
the process, which is questionable ... :) ).
