Possible to add additional Linux drivers?

Hi all, I noticed that with recent firmware updates USB keyboards are supported. I was wondering if it was possible to implement 3rd party Linux keyboard drivers? The one I’m particularly interested in is xboxdrv ( found at http://pingus.seul.org/~grumbel/xboxdrv/ )which features support for chatpads. Being able to use a compact backlit keyboard would be awesome for me, but I personally don’t know how I would go about putting this driver on the WDTV? Is it at all possible to accomplish this?

Thanks in advance to anyone who can guide me with this.
