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?
