Thanks for asking.
It appears one debug logging option has slipped my attention when 
building the latest release - responsible for all entries starting 
with RBIOKitDriver. Sorry for that.
 4/17/09 8:26:53 AM kernel [0x588aa00] RBIOKitDriver::init - entered
  I've just uploaded a silent update that includes a version of the 
Remote Buddy driver without the debug output. Please
1) download a fresh copy from Remote Buddy at
http://www.iospirit.com/remotebuddy/download/
2) replace your current copy of Remote Buddy with it
3) select the Setup Wizard from Remote Buddy's menu and reinstall the 
driver to replace your current copy with the debug output.
The other entries, however, don't appear to be related to the Wii Mote 
(and thus Remote Buddy) at all. At least I'd be surprised, because the 
BD Addr of Wii Remotes usually looks different and Remote Buddy also 
doesn't try to establish a connection at such a high frequency. It 
seems to be a different Bluetooth device and software:
 4/17/09 8:40:40 AM com.apple.blued[63] Create connection failed 
(0x4) for device: 00-1B-7A-3F-80-7F
To find out which device it belongs to, open System Preferences.app, 
click on Bluetooth. Now use the gears popup button below the table on 
the right to enable "View more information". Then click on one device 
after another. You can now see the BD Address of the device in the 
table on the right. Look for 00-1B-7A-3F-80-7F to find the device in 
question.
Best regards,
