Perhaps I missed the discussion; but .. out of general curiosity,
what is the relation between this and the ppc_md.nvram_* system?
I note that pseries, powermac, chrp, celleb implement the nvram calls,
but cell and ps3 do not. So clearly, whatever this is, its not 
layered on top of nvram?

FWIW, I don't quite understand the nvram system; it seems to have
partitions; one part is an "os area", and a chuck of it is set 
up as a file system.

So I'm wondering -- wouldn't the DB os-area be "generically 
interesting" to other ppowerpc platforms? Maybe even other arches?
And why isn't this built on top of the nvram structure? ... etc?
