10 Argh, my failure. I must have read "19.5 kHz" instead of 15.9 kHz, so
11 try a HorizSync of 15-16.
12
13 The exact frequency can probably be calculated from the modeline:
14
15 Modeline "736x485i" 14.16 736 760 824 904 485 491 496 525 interlace -hsync -vsync
16
17 would be
18
19 14.16MHz / 904 "virtual line lenght" = 15,66 kHz
20
21 I've also read values like 14.35 MHz for the pixel clock.
22
23 The i810 should work for pixel clock frequencies >= 9,5 MHz (the driver
24 sources tell that), so it *should* work.
