Is your keyboard plugged on USB?  Assuming it is, then again this 
could be because your device is too new and the pci id and / or extra 
code to support your device is missing.  

We have not tested OK Linux with your version of Ubuntu and it is
possible that the OK Linux kernel is too old or incompatible with
your version of Ubuntu in some way.  The last Ubuntu we got running is 7.10.
