Tracker bug for my NV40 randr issues to keep stillunknown happy :)

First up: GPU panel scaling

The default panel scaling option produces bad looking modes.  There are white
lines across the width of the screen, in some modes it appears to be a gradient
of white then a line or two of the "correct" image, then more white
gradients.

Attatched is a log of starting X then:
darktama at beleth:~$ xrandr --output DVI-D-0 --mode 1024x768
darktama at beleth:~$ xrandr --output DVI-D-0 --set SCALING_MODE panel

After setting the scaling mode to "panel" the image is correct.

As i asked earlier, a mmio-trace trying the various scaling options in
nvidia-settings would help.

The issue no longer appears to be present with current git.  Closing bug.
