Right-o.  I found a discussion thread regarding trying to put a filesystem
on NVRAM - not what I'm trying to do.  I'll look more closely at the kernel.
What I would like to do is have support for the /dev/nvram node.  That's
what I was referring to when I stated there was no PPC support in the
nvram.c file.  Thanks for your suggestion.

Tom

Try looking in arch/ppc/kernel - that's where the RTC/NVRAM support is (in
the 2.4 kernels at least)
