Running `dpkg-reconfigure xserver-xorg' resulted in a much smaller
xorg.conf, and the problem went away. It also went away when removing
the VertSync option, because the VGA-0 output then supported a 1024x768
resolution.

The VGA output is still there, but it causes no harm. I suspect that the
problematic patch might actually have the benefit of enabling VGA output
on my laptop by default, so 1024x768 projectors will now just work.

My xorg.conf is managed by dexconf; perhaps trigger a reconfigure of
xorg.conf on upgrade of the ati driver...? But then, a lot of people
have the ati driver installed but use a different one.

So perhaps the only safe solution is to actually detect when VGA devices
are attached.
