Yes. However, I thought you were upgrading from an earlier kernel, and as
pcmciautils is really new, I thought you might still have a pcmcia-cs based
setup...

Actually, it should be called by the hotplug system automagically upon
modprobe yenta_socket, with the socket number as argument.

Actually, it expects one argument, the socket number. It doesn't do any
argument checking, so it simply tries to convert "--help" to a number. That
results in the number "0", so the socket numbered "0" is started. I've fixed
pcmcia-socket-startup to start _all_ sockets if no argument is given.
This'll be part of pcmciautils-009 which I hope to release soon.

You need to get the CIS file from pcmcia-cs it's in etc/cis/, named ".dat",
and needs to be re-named to ".cis" and put into /lib/firmware, IIRC.

Excellent, thanks!
