Once in every so often boots I end up in X without a functioning mouse. A
pointer is shown, but glued to the center of the screen. A reboot will fix it,
but I have had this behavior for a few years now and still no clue what the
origin of the problem is - dmesg reports as it does normally:

PNP: PS/2 Controller [PNP0303:PS2K,PNP0f03:PS2M] at 0x60,0x64 irq 1,12
mice: PS/2 mouse device common for all mice

killing and restarting X and/or gpm doesn't return control over the mouse.

I have been storing dmesgs at failures:
2007-08-29
2007-09-15
2007-11-23
(I boot twice a day on average)

As you can see, I had one recently. This time I also made a copy of my /proc
and /sys directories. (I am guessing /proc was not really needed) maybe any info
can still be extracted?

Where can I look, what can I do to find the source of this problem? Is there
anything that I should do to obtain more info when this occurs nexttime?

Thanks
