For your ION2 system, there's a relatively easy workaround.
Just hook the TV up so that it is "seen" by the box,
and then extract the EDID information from it (use nvidia-settings).

Then just supply the saved EDID to the driver at each boot,
by issuing these commands (once, ever):

  nvidia-xconfig --custom-edid=/path/to/saved/edid_file
  nvidia-xconfig --connected-monitor=Monitor0
  ## "Monitor0" must mach monitor "Identifier" in /etc/X11/xorg.conf
