console keyboard lock

[seweryn]

I have kernel 2.6.20, on Fedora Core 6 with udev 095-17.
On text console, incidentally I pressed mangle combination of keys ( something
like Alt + F9 ? ) and after that my keyboard freeze ( no action on any keys,
even turn light on with Caps Lock pressing ). One message published to syslog
when this happened:

kernel: input: AT Raw Set 2 keyboard as /class/input/input4

and nothing more.
Normally, after system starts my keyboard is initialized as:
input: AT Translated set 2 keyboard as /class/input/input1
System work fine, only console keyborad is out of order.
What happened and how to unlock console keyboard ( I may work on this
system from another computer via ssh terminal ) ?

If I run kudzu to test hardware I got two keyboards :
$ kudzu -p -c KEYBOARD
-
class: KEYBOARD
bus: PSAUX
detached: 0
desc: "AT Raw Set 2 keyboard"
-
class: KEYBOARD
bus: PSAUX
detached: 0
desc: "AT Translated Set 2 keyboard"

Finally, I didn't able to solve this problem and I must reboot server. After restart all works properly, system discover only one keyboard, like before accident. At now I don't have environment to test yours advices, so don't write it.
