I have the same problem on a fully updated etch installation. I tried pairing with many different settings of hcid.conf (including auto) but every time it failed with a call_passkey_agent(): no agent registered message in /var/log/syslog. Then I found this bugreport and tried the unsupported hack and it worked in one go (so thanks for that!). I do have the complete debian metapackage "bluetooth" installed, including bluez-passkey-gnome, which didn't help in solving the problem in my case apparently.
I am also running Fluxbox and don't see any bluez-passkey-gnome icon, but perhaps that is because I should have done something especially to achieve that. Keep up the good work. Bram -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
