I don't remember any really big X-related update in sid in the last
month, at least regarding the server core and mouse driver.

xserver-xorg-core would be the first candidate. Then drivers. Then libs.

I would have voted for the kernel too.

Did you try both /dev/psaux and /dev/input/mice?
You could try running "cat /dev/psaux" or "cat /dev/input/mice" as root
while moving the mouse. If the kernel is fine, some ugly characters
should appear in the terminal.

Looks like you need to install libgl1-mesa-dri (unrelated to your problem).
