Title:
Screen flickering in Intel i915 driver
To manage
Seeing the video again and based on recent issues I faced I believe this could
be watermark related...
So, could you please apply http://patchwork.freedesktop.org/patch/69417/
and boot with i915.enable_watermark=0 and let us know what happens?

drm/i915: Fix TV Out refresh rate.
TV Out refresh rate was half of the specification for almost all modes.
Due to this reason pixel clock was so low for some modes causing flickering
screen.

The flickering appears always for any pclk 20, independent of screen
resolution or refresh rate.
I could reproduce with 2 different boards: 945GME and 82945G/GZ.
On the first one I had to add newmodes forcing the pclk = 20 in order
to avoid the flickering:
xrandr --newmode 640x480_20 20 640
