Something is wrong with the options node in OpenBIOS. It is

I'm not certain what the problem could be.

Try using /chosen instead of /options.

The latter is special, it's nvram stuff, it could be that OS X treats
it specially too.


When I use the -prom-env option I can easily add properties to the options node.
Can something like this be done with the chosen node?
