Forgive me for stating the obvious, but the best way to make sure that a
PC card adapter is not using power is to physically remove it prior
to power-on!
But if you want to logically turn it off, here's how. (The pound
sign represents the root shell prompt. It is not to be typed as
part of the command, which would of course make it a comment!)
# ifdown <IFACE>
# pccardctl eject <socket>
As for wifi, I don't know. I have no experience with wifi under Linux
as of yet.
