These are mostly messages from gpm
Oct 20 14:23:47 d_baron /usr/sbin/gpm[4547]: *** err 
[daemon/getmousedata.c(47)]:             
Oct 20 14:23:47 d_baron /usr/sbin/gpm[4547]: Error in read()ing first: No such 
device         

This is a microsoft wireless usb mouse. Sometimes, the receiver needs be reset 
but this is occasional. Gpm was not upgraded recently?

How might one surpress these log entries? They are of little value.
