Jörn,
   In 99% of the
cases it's a fucked up Cardbus controller. Did the card
 ever work on this particular notebook with a recent kernel? 
 are there reliable
black or whitelists around somewhere?  
 
Google? :) Seriously, none I know of.
  asking because
 i might be shopping for a recording notebook early next year, and the
 madiface is sooo cool :) 
ExpressCard is not so much an issue. Still I had problems with the
PowerManagment of the Centrino2 chipset in my Thinkpad X200. After a
BIOS update, the problem was gone.
