10.6.8 MacPro Bluetooth stuttering

Problem description:

After upgrading to 10.6.8 and after some minutes working I realized my keyboard input was faster than the text appearance on screen. Sometimes I push a key on the keyboard and three or more times the letter appears on screen. Then I noticed the mouse movement on screen was stuttering, not constantly, but sometimes more, sometimes less; but no serious work possible. If I switch off Bluetooth and switch it back on, I have a few minutes for normal behavior of my Magic Mouse and keyboard, but then same problem again. Urgh.

What I've done so far:

- Repaired permissions

- Deleted both devices from the list of known Bluetooth devices and registered them again

- Deleted the bluetooth.plist

- Reset the PRAM

- Reset the SMC

- Installed the Combo Update for 10.6.8

- Switched the channel of my Wireless base station (tried every single possible channel)

Seems like a Bluetooth buffer overflow if I look at the last Kernel messages ... 😕

Thanks for every help, if there's a way besides installing the whole system from ground up. 😠
