Not sure if this is intentional or not. /sbin/cardctl has
become suid-root in BETA3. It isn't suid-root in RH7.0.
Ages ago we removed the suid bit from the binary, so
I'm wondering if a packaging error has crept in.
Fixed in 3.1.23-0.6. It fell out when we switched to building it as
its onw source package.
