Actually, in pre-rc1 versions, mouse visibility was always limited
to the outer edge of a terminal if it existed, yet never exceeding
the 640x460 visibility. 
Don't think it matters, but trying to be precise.

This was a plain coincidence. The message is contained in the dmesg
of the last working commit as well. Sorry for the red herring.
