Should work.

pccardd must be running, or you won't get the above line :-). At
least not the one after pccard: card inserted. Chances are good this
is an IRQ problem. Can you send me the output of boot -v so I can
check it against the datasheets? Don't have a card in the laptop when
you do this. I'm most interested in the cardbus config space part of
the output if you can't save it all.
I've seen problems with this in two ways. One when you pickeda bad
management IRQ. One when the bridge is misprogrammed. I think the
former is happening, but maybe the latter is happening.
