I have the same problem on my mobility X1400 (aka M54).

Like the OP, I can attach a VGA after X is running and use xrandr to enable it,
but if I restart X, by logout or reboot, with the VGA attached, then I get a
black screen on the laptop and VGA.  The same happens with the S-video out (see
comment #4 on bug 16178).  I can attach it after X is running and use xrandr
with it, but logout or reboot results in a black screen on both.

One difference than the OP, I can use Cntl-Alt-Del to reboot.  However the
consoles do not work (i.e. Cntl-Alt-F1).

Another difference is that I have not had any freeze when connecting or
disconnecting a VGA or S-video.

Another difference is that I do not have any resume problems.

I'm running ubuntu hardy with git packages from the tormod xorg-pushers
repository (xserver 1.4.99.906, mesa, libdrm, and ati from git) and I also
upgraded libxrandr to 1.2.3.

By the way, I enabled S-video by undoing your disabling patch, so I could test
it.
