Redhat-6.0 fails to detect pcmcia on a thinkpad 310E laptop, so installing/upgrading is impossible. Even in expert mode, there is no way to force loading of the pcmcia modules. linux/pcmcia-cs has no trouble detecting the pcmcia slots, so it must be a flaw in the red hat installer. Non-redhat can be installed with no problem: # cat /proc/pci Bus 0, device 4, function 0: CardBus bridge: Texas Instruments PCI1131 (rev 1). Medium devsel. Master Capable. Latency=32. Min Gnt=192.Max Lat=7.
Does the installer still fail to detect the pcmcia bridge if you have Cardbus support disabled? You can disable it by going into the BIOS (hitting F2 while turning on the machine) and then go to System Security, disable CardBus support then back out with the ESC key til you are asked to save the new settings.
