That was actually the only problem. It came up when I replied to a post 
from someone asking how to get an SMC card to work. You send a msg back 
to me asking me to run the 'pccardc dumpcis' command and send you the 
output. Since the 'pccardc ...' command didn't work, I got the info 
using Slackware Linux, which I've got on the second slice, and sent you 

In this thread I was essentially trying to provide info for the 'pccardc 
dumpcis' command, since it seemed to be broken in some way or another. 
But if it's deprecated, that's a whole 'nother story.

My -current is about a week old, so I cvsup'ed another just now. I'll 
rebuild everything and try the command you suggested.

Thanks for your quick reply,
