I realize that, but I'm trying to cut down on "resident" apps to see if I can pin down the one(s) that make(s) my tablet reboot on its own now and then, and/or chew down its battery overnight, in both cases while sitting idle with the cover on.

The chief suspect, for me, is the swap file -- I'm almost sure of that one. The next is the BT plugin. Or maybe a combination of both. So I'd gladly take a driver like fanoush's, that I can load and unload at will only when I need the keyboard, just like with the CIFS scheme...
