agreed, I've fixed this in
http://svn.debian.org/wsvn/pkg-bluetooth/bluez-utils/trunk/debian/bluetooth_serial?op=file&rev=0&sc=0
and
http://svn.debian.org/wsvn/pkg-bluetooth/bluez-utils/trunk/debian/bluez-pcmcia-support.udev?op=file&rev=0&sc=0

agreed but since the script is (supposed to be) invoked only by udev on
add/remove pcmcia bt cards, I think we can assume the script is the only user of
$DEVNAME.
