Then the bug is not in X. If psmouse is loaded and events don't appear
in /dev/psaux or /dev/input/mice, something is missing in the kernel or
so. Did the ps/2 mouse ever work before installing this Debian? In
another Linux? In Windows? Any BIOS option to enable it?

evdev is the X driver, X is not involved at all when doing "cat
/dev/foo", only the kernel is (and udev when creating the file).
