Ah. Damn. (If SunOS could do it, why can't Linux?)

Well, I've just discovered that the system won't boot if I put the flash card
in the second PCMCIA slot and card services are enabled --- it says:

cardmgr[243]: Card Services release does not match
cardmgr[243]: initializing socket 0
cardmgr[243]: socket 0: Grey Cell GCS2000 Ethernet
.
Starting kernel log daemon: klogd.
Starting NFS common utilities: statd.

nfs: task 2867 can't get a request slot
nfs: task 2868 can't get a request slot
nfs: task 2869 can't get a request slot

If I try it without pcmcia-cs, it all seems to work and I get lots of
/dev/hda entries; but none of them are openable. The relevant messages are:

Sigh. Any ideas?
