Hi,

(sorry, must have overlooked your last answer...)

Argh, my failure. I must have read "19.5 kHz" instead of 15.9 kHz, so
try a HorizSync of 15-16.

The exact frequency can probably be calculated from the modeline:

Modeline "736x485i" 14.16 736 760 824 904 485 491 496 525 interlace -hsync -vsync

would be

14.16MHz / 904 "virtual line lenght" = 15,66 kHz

I've also read values like 14.35 MHz for the pixel clock.

The i810 should work for pixel clock frequencies >= 9,5 MHz (the driver
sources tell that), so it *should* work.
