Not quite.  I do have some code somewhere that needs to be cleaned up
and integrated that would allow some access to flash like a filesystem.

There is currently no support for either right now, though.  The
nvram should probably have a simple device for access.  I'm not
quite sure how to talk to this--it's not something I've really
looked at yet.  I expect that both DINK and ppcboot do read/write
it, though.
