The next version is almost finished. 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?

Regards,
Steffen
