Determine time of last keystroke and mouse movement

[Orion Poplawski <orion cora nwra com>]

Is there anyway for periodic (cron like) job running as root on Fedora 
10 (and up) to determine time of the last keypress and mouse movement? 
Back in the day I could look at the access time of /dev/tty7, but this 
appears to be no longer the case (even when moving to /dev/tty1 to 
account for the vt1 X shift).  Any ideas on how to determine this would 
be greatly appreciated.
