Yeah that isn't really surprising.  Essentially
arch/powerpc/platforms/powermac/nvram.c must be builtin (not modular)
but CONFIG_NVRAM is tristate, and your .config has CONFIG_NVRAM=m.

We can probably "fix" this by adding another config config symbol and
"selecting" that from CONFIG_NVRAM.  Then using this new symbol in
arch/powerpc/platforms/powermac/*

so I think with we need is:
config NVRAM
  bool "..." if PPC32
  tristate "..." if !PPC32
  ...
  ...

Sam is there some way to achieve that or should we just create an
secondary symbol?

Yours Tony
