This is because psaux mouse devices weren't handled by the input subsystem in Linux 2.4, but are in Linux 2.6. The only real fix for this, as far as I can tell, is to have an init script that records the running kernel version at system boot and checks the stored value (from the previous boot) against the current one. If the user uses a psaux mouse and moves back and forth between 2.4 and 2.6, the XF86Config-4 file will have to be rewritten. Fortunately, having such an init script is a good idea for other purposes: it would be nice to perform some hardware detection relevant to the X server, and if the state of the system has changed, have the user reconfigure the X server (under ideal circumstances, this reconfiguration could even be noninteractive). -- G.
