Grr. I was just working on modifying this ioctl() to return
something better than int[5], which is pretty ugly.

How about something along these lines (I have the rest of it - its
just trivial changes to evdev.c)?

I could live with curr, min and max instead of *_value, but it
would be nicer if it was a bit more descriptive.
