Doesn't work with that either but maybe the nvram is in wrong format. QEMU 
mentions it's using CHRP NVRAM format which works with OpenBIOS and SLOF:

https://git.qemu.org/?p=qemu.git;a=blob;f=hw/nvram/chrp_nvram.c;h=d969f267048e626007d284dcfa72844ddcd61c84;hb=HEAD

but maybe old world OpenFirmware uses something different. I've also tried 
if not putting anything in NVRAM is better as it may be confused if 
something unexpected is there but that does not help either.

I'm not on this list and cannot access archives so please make sure to cc 
me on any replies in case these messages go to the list and someone 
replied there.
