[Intel-gfx] VGA to PAL RGB

[Thomas Elsen]

Hi all,

I'm trying to get the following modeline to work with my Mythbuntu. This 
modeline should be perfect for television sets that understand PAL.

Modeline "768x576pali" 14.76  768 789 858 944  576 580 583 625 -hsync 
-vsync interlace

My TV is connected with a custom made cable the joins the horizontal and 
vertical sync signal.

The problem with the current drivers is that the minimal dot clock is 
defined as 25Mhz. I'd like to know if this is a hardware limitation and, 
if not, what should be done to run the clock at 14,76Mhz.

Best regards,
Thomas Elsen
