thank you very much for reading through the hardware docs!

I would really appreciate upstream interlaced mode support on VGA/DVI for several reasons: - the patch above (originating from Krzysztof Halasa) works fine for at least i810e, 915G, 945G, 965GM chipsets - adding interlaced mode support won't break existing applications - for boards like Intel D945GCLF this is the only way to connect a SCART TV-device without the need for additional hardware - signal quality on VGA/RGB is superior to S-VIDEO - support for variable frame rates allowing to deinterlace by display hardware: As mentioned here: http://lists.freedesktop.org/archives/xorg/2008-September/038296.html I wrote a patch for older ATI-radeon type cards, which synchronizes VGA/DVI output timing with external signals. This is an essential feature for jerkyless playback of live TV. I'm currently porting this to intel 9xx-class hardware hoping it will work there as flawless as on radeons.
