unregister_netdevice wlan error

I have a RH9 (2.4.20-20.9) laptop that's used both at home and work.  At
home, I use the linux-wlan drivers (prism2_cs.o) with my D-Link prism2
pcmcia card (wlan0), tunnelling the session over an isakmpd IPSec
connection (FreeS/WAN 2.04).  Everything works fine...

About one kernel upgrade ago, I started noticing errors to the console
at shutdown that would stop the laptop from being able to poweroff
cleanly.  This "unregister_netdevice" error appears to only occur when
IPSec is installed, so I wonder if something isn't shutting down cleanly
with ipsec/klips before the cardmgr tries to release (I'm grasping at
straws here).  As it is, I have to load the ipsec service via rc.local
so as to avoid pcmcia startup delays.

Google has a number of hits on that error, but nothing that makes any
sense.  Anyone out there run into this?  Any ideas?

Thanks,
