ath on pci should cover cardbus (does on FreeBSD at least).  Thinkpads w/ 
minipci mostly work; there are some issues.  Some have an rfkill switch that 
needs some support in the driver that isn't present yet.  Also, some machines 
use different PCI device id's and some BIOS support in an effort to force 
only "approved drivers" to work with the cards.  We're working out this issue 

If you sift the mailing lists for the madwifi project at sourceforge you can 
pickup some useful stuff in this area...
