Lost keyboard in fedora-release-9-2. in X

[John Summerfield]

System: HP DC7700
OS fedora-release-9-2, AMD-64.
Last updated within the past two houes.


I logged in at runlevel 5 using KDM, choosing icewm or fvwm.
On logging out, the mouse continues to work fine, but the keyboard not 
at all. No keypresses, no lights toggle when I press appropriate keys.

Switch to a VC (using the mouse, <ctrl>-<Alt>-F1 does not work), 
keyboard and mouse are fine.

Recovery:
telinit 3;sleep 10s;telinit 5.

Nothing obvious to me in
/var/log/Xorg.0.log.old
