When I remove the card, the whole
system hangs. Totally -- can't log in from the network, if top is running it
stops, etc. Have to do a hard reboot. I've tried installing the latest
pcmcia-cs. Otherwise pcmcia works fine, it correctly ID's the flash card I put
in, reads it, writes to it.
Here's what it says in /var/log/messages when I insert the card:

Sep 3 21:01:40 cybershamanix cardmgr[1516]: socket 0: ATA/IDE Fixed Disk

So I can can then mount /dev/hdc1 on /mnt/temp, read it, write to it, then
unmount it, pull out the card and bam! the machine locks up.
