Not much to offer, other than 2 PCMCIA cards work as expected on 5 laptops, both i486 and x86_64. The laptops are Dell c600,c800,c840,d830 and a Compaq Armada m700. The cards are a Linksys wireless adapter, and a 3Com ethernet adapter.
I'd look at /etc/pcmcia/config.opts explained here
Google wasn't much help, though there were some reports of polling issues with different Fijitsu notebooks. Sadly, these reports were all quite old, dating to kernels 2.2-2.4.
