With a 2.036 kernel and a US Robotics 33.6 modem + ethernet PCMCIA card,
the warning below (marked by <<<<<) during boot, and as later displayed
by dmesg.
Manifest decrease in functionality is not evident, but it would be nice
to understand it.

Grepping the source code reveals:
stodolsk:/usr/src/modules/pcmcia-cs# grep "cs: warning" */*
grep: clients/patches: Is a directory
grep: etc/cis: Is a directory

Any insight as to what the warning reflects.
