My laptop crashes when I remove the cardbus card:

I've found two workarounds:
* disable "com* at cardbus?" with userconf.
* boot the system without the card inserted and insert the card when
the system is up (the com3 doesn't say: "com3: interrupting at irq 11").
The card is a Xircom RealPort Cardbus Ethernet 10/100+Modem 56.
