Please see the "Sun NVRAM/Hostid FAQ", available at:
http://www.squirrel.com/squirrel/sun-nvram-hostid.faq.html
For the short-short version, if your NVRAM battery is dead, you can do the
following to resurrect it until power-off, at the PROM prompt:
> n (go to new command mode if necessary)
ok 0 f mkp
ok 8 0 20 AA BB CC AABBCC mkpl
^D^R
ok
AA, BB, and CC are octets of your choosing. ^D^R is Ctrl-D Ctrl-R. If you
get a Sun copyright notice instead of just `ok' after the mkpl, chang the
`0 f mkp' to `1 f mkp' and try again.
I'll be closing this PR now. This is not something appropriate for patching
the kernel, as an invalid IDPROM can cause you other troubles and you
_should_ fix it at the PROM prompt and not in the kernel.
