Oh, and "while you're in there" would I be able to talk you into relaxing the input checking of the SETGEOM ioctl a little bit? There are times when I'd like emphatic to be the "foreground app" but completely remove itself from the screen. Currently my only way to do this is to use a 2x2 pixel square like this:

hijack_geom_t corner_geom = { 30, 31, 0, 1};

Ideally I'd like to just pass in { -1, -1, -1, -1} or something to say "I don't want to be on screen at all, but I'd like to remain running." Also, you have checks to make sure that left < right and top < bottom. IWBNI it was left <= right and top <= bottom to allow for a geometry of, say, { 0, 0, 0, 127} (the top line of the display.)

I know these sound like strange requests but these actually would help me out. I can do a patch if it pleases the court.
