Non-AES fingerprint reader swap on X200 tablet???

[piledriver]

The NON-AES Authentec fingerprint readers can be set up like ~touchpads, similar to the newer Blackberries (but much larger sensor, and programmable)

Has anyone swapped in one of those ?
I suspect it would make for a handy touch input alternative in tablet mode on my pen-only X200T.

I'm actually hoping there is some trick to get the std one to work that way i'm missing, just spent some quality time pulling it out and making sure it was plugged in before I found it disabled in the BIOS>I/O access menu wayyyyy down at the bottom. (have to scroll)

At least I know for sure I have the cable for the webcam...(kept digging)
