TLDR: A T60 with a 945GM/GMS(?) controller works without that patch with Linux
3.2.x.
I am petrified. Testing this TV with a T60 and a different VGA cable (all pins
populated, instead of Pin 9 missing) everything works fine (besides a little
vertical shift to the right). :/

So I am puzzled. Could it be a specific problem to the chipset 915GM?
