Tumnus,
If you ever make another release of the bluez package, maybe you could include a post install script that tests if /etc/pcmcia/bm3.conf exists, and if it does, renames it to /etc/pcmcia/bm3.conf.bak (if the extension changes, it won\'t hurt anymore). Then, the post-uninstall script could do the reverse.
That would make it work out of the box for 6000 owners, and stop these questions.
