This is expected.  pccardc dumpcis doesn't work, and likely will never
work again.  It is part of the old pccard support.

If you have current as of today, however, you can run 'pccard
dumpcisfile /dev/pccard0.cis'.

It is likely a warning that can be ignored.

pccardd is deprecated and isn't needed.  It should just work.

: Anyone have an idea of what's going on here? I'd be happy to try any 
: patches anyone may have, or to provide more information if necessary. In 
: the meantime, I'll keep looking into it.

Other than not being able to dump the cis, what's the problem that you
are having?
