Yes, if things do try and access the NVRAM directly then that would 
definitely be a better solution (I had no idea that QEMU did this until 
I read your previous email!). It's not particularly on my radar at the 
moment as I'm back deep in SPARC64-land, but I'd be happy to support 
anyone that did come up with something suitable.
