Alan,
One more thing. I was able to reproduce it once during an initial powerup sequence by putzing with the mouse buttons while the auto-detection was going on (generating interrupts?). I am wondering if the problem in in the way interrupts are being handled for the mouse. If I leave the mouse alone it seems to get autodetected properly.
