I'm using a Vaio SZ2HP and I have exactly the same problem (though I don't really know what triggered it.
In my case, the problem was solved by following the instructions in:
http://www.pihhan.info/sony/sony-hotkeys.html

In particular, all I did was:

1) lshal | grep 'system.hardware.product'
2) edit /usr/share/hal/fdi/information/10freedesktop/30-keymap-module-sony-laptop.fdi
3) add the string to the list of models (In my case it was 'VGN-SZ2HP_B')
4) sudo /etc/init.d/hal restart

and it was working.
The attachment contains the fix for my problem.
