All cardctl commands seems to working when run manually.

So I added 1 s delay before rmmods, and now the pcmcia script works
correctly and the kernel doesn't panic. By doing service pcmcia restart,
_all_ related modules are unloaded and thus no "cs: unable to map card
memory!" messages.

if grep -q "ds " /proc/modules ; then
	/sbin/cardctl eject
	/bin/sleep 1

	/sbin/rmmod ds
	/sbin/rmmod $PCIC 2>/dev/null ||
            /sbin/rmmod yenta_socket 2>/dev/null
	/sbin/rmmod pcmcia_core
fi
