After having used tv-out.  To reiterate, this is what I'm doing: X starts with
the DVI and VGA outputs enabled.  I disable the VGA output and enable the TV
output.  I then disable the TV output and enable the VGA output.  X believes
that the VGA display is enabled (the desktop adjusts itself to having more
space) but the monitor just says "the input signal is out of range."

I've attached register dumps in the working state (after startup, before
disabling the VGA output) and broken state (after disabling the TV output and
trying to enable the VGA output.)
