Probably a bisect on drm-intel-nightly is less painful.
But it seems that we are indeed now duplicating the discussion and there is
more information on the other bug. Please reopen if you believe this one here
is a different case.

Another bisect attempt would be ideal.
Since it happens with i915.enable_psr=0 it is not PSR related.
But anyway, could you please provide more info about your system:

Given it happens even with i915.enable_psr=0 I'm sure the bisect was
misslead at some point.
I'm starting to suspect on Watermark.
Could you please try to apply the following series to see if it helps:

what about i915.enable_psr=0?

TV Out refresh rate was half of the specification for almost all modes.

To manage
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
