I have a USB keyboard (EMPREX 5139U) which, with the 2007.2 (I think), the 
LEDs would not light up, but I could use it on the console (and not in X, but 
due to other things).  It works fine with my PC, and with the FR now that I'm 
running Debian (though it doesn't keep the FR from dimming the screen).
