I see. For now I assume it's the same for i830 and later only.

Yes. Actually it's now perfect, I don't mind extra 25 IRQs/second.
Thanks for the info.
FYI: I'm using Linux FB driver (drivers/video/intelfb) for experiments
and now the display is flawless, I get full PAL with correct field
order and full resolution, in sync with the video stream etc.
It's not using hw color space conversion nor hw X scaling (I double
X resolution because i915 can't do 13.5 MHz pixclock, but can do 27 MHz),
It's not a problem as long as the display is ok.
Now I have to look how to get that to X.org driver too (and, obviously,
