I'm not completely sure what's best here, so I kept it enabled by 
default and optionally disabled. Otherwise I'm afraid it's unlikely the 
backend will be used at all, and that bugs may only be discovered late.

But maybe it's better to disable it for now and only enable it by 
default once it gets actually a bit usable, which should not take too 
many patches, if we ignore force feedback support.
