[CentOS] PCMCIA not working on IBM Thinkpad r40

I am running Centos 4 on a Thinkpad r40 and it does not see any pcmcia 
cards.  I know the socket is good because I had it working with Fedora 
Core 3.  A funny thing though, once I updated my fedora kernel to a 
certain rev. (don't remember the version) the card socket no longer 
worked.   Going back to an un-upgraded install of Fedora 3 worked.

Has anyone seen this problem and worked this out with Centos?
