[Bug 78562] [gma500] wrong pixel clock on LVDS (half the correct frequency)

--- Comment #14 from pmarques at masterguardian.com ---
One thing I noticed on the Xorg.log I posted is that at some point it has this:

...
[    25.686] (II) modesetting(0): Modeline "1024x768"x30.1   32.57  1024 1048
1184 1344  768 771 777 806 (24.2 kHz P)
...

So, it seems that the system knows it is working at 30.1 Hz (instead of 60Hz),
but all my attempts to use xrandr to convince the display to go to 60Hz didn't
work. I don't rule out that I might have been doing something wrong, though.

I can try to look at the code, but all the code under "drivers/gpu/drm/gma500"
is around 30k lines. can you at least give me some pointers at which files I
should look at first? Are they even in this directory?
