[PATCH] nvidiafb: Add flat panel dither support
nvidiafb didn't fully hook-up the code it borrowed from X for doing flat panel dithering (this is useful for 6 bits panels). This adds a driver option to force it, and by default "reads" the current value from the chip to get the firmware setting. It significantly improves the quality of images on the iMac G5 I have here (though the X driver doesn't yet "read" the current value and defaults to 0, so you have to add Option "FBDither" "true" to your X config file to get that, I'll try to fix X.org to "read" the default unless specified asap).
