Yeah, expected, though certainly verbose.  That gets printed every time
we scan your monitor, which is at least twice as often as it needs to be
on startup, and then again every time something asks RANDR what the
current output configuration is.

I've wanted to do a patch for a while now that compares the EDID block
received on each successive scan with the previous one and skips the
verbose printout if they match.  Anyone want to beat me to it?
