Same problem, the information there is driver specific and the
tool currently use a fix offset instead of properly handling the
nvram device tree extension format (afaik). The cmode is also a
driver specific thing and is equivalent to the MacOS driver
"DepthMode" setting, which will map differently to bit depths
depending on the MacOS driver you are dealing with.
