Up-arrow error message in Breezy

[John Nicholls]

In Breezy pressing and releasing the up arrow key produces these errors 
in the system log:

Dec  6 17:00:56 localhost kernel: [4310260.318000] atkbd.c: Unknown key 
pressed (translated set 2, code 0xaa on isa0060/serio0).
Dec  6 17:00:56 localhost kernel: [4310260.318000] atkbd.c: Use 
'setkeycodes e02a <keycode>' to make it known.
Dec  6 17:00:56 localhost kernel: [4310260.435000] atkbd.c: Unknown key 
released (translated set 2, code 0xaa on isa0060/serio0).
Dec  6 17:00:56 localhost kernel: [4310260.435000] atkbd.c: Use 
'setkeycodes e02a <keycode>' to make it known.

The key works as it should but these error messages clutter up the 
syslog. The keyboard is a standard 104-key US English. This does not 
occur on the same computer with Warty or Hoary.

Any suggestions?
