I just hot-upgraded my laptop from 2.1-PAO to 2.2.5, and now it's off
the net --- it seems that the pccard driver no longer accepts "default"
and "any" for interrupts and memory locations, but wants specific numbers.
Which seems like a big step backwards if you ask me, but I haven't yet
gotten a chance to track down what's going on, so don't consider this
a bug report or a complaint yet (unless you know for sure that this was
what was supposed to happen :-) ).

On a production system, I would never hot upgrade...
