* prep for 2.6.35 and a coexisting "sii9022" driver from Freescale by calling ours "siihdmi" as per the filename
* never put the chip into D3 power off state if we cannot hotplug the chip out of it
* semi-catch setting a mode with a null fb_videomode argument, since this is impossible to perform (there may be other places this needs handling, and there should be a healthy fallback)
* don't perform fb_videomode_to_var for screen blanking, and simplify blanking functions to not require fb_videomode_to_var since they do not actually use them
