GDB log of crashed X server

Somehow I have been recently getting crashes in miPointerMoved due to the miPointerScreen devPrivate being set to NULL. Attached is a GDB log.

A patch to work-around the crash

This is a patch I've been using to work-around the bug although a more thorough solution is probably necessary. I can't imagine why the devPrivate would be set to null. Note that this occurred with a USB mouse plugged in to a port that is sometimes flaky. It is possible that the device was being "added" and "removed" fairly frequently.
