Only thing I'm missing is this. And I actually do not know which flag would represent an inverted pixelclock in fb_videomode. Does anybody have any idea what I have to do here? if (vm->pixelclk_pol) fbmode->sync = ??? That's as far as I have come and I don't see a flag that seems right. Is this even a valid property of fb_videomode?
