I think this is causing the build errors.
Do you have nvram.o?

In the config you send earlier you had:
so generic_nvram.o should have been build. Is this still the ".config"
file you have?

Check your Makefile and Kconfig in drivers/char. Not sure what to tell
you to look for... something wrong...

Ok, have 2.6.5 here. Should be close enough.

Yes, looks good. But if CONFIG_GENERIC_NVRAM is not set (or it
thinks so), the code won't be compiled.
