at least the VGA-to-SCART cable (not yet the patch itself) does run here
on nVidia hardware without problems. Box is a PUNDIT P1-AH2 with nVidia C51PV

really? On my Pundit I use NVIDIA-Linux-x86-100.14.19-pkg1.run and
the attached xorg.conf with no problems.

I just use one big hammer instead:)

Option "UseEDID" "FALSE"

That works (mostly).
