Don't think so. Unless nvram is just a curiously renamed and retasked pram,
which I seem to recall it isn't, then 68k macs don't even have it.

The pram/rtc, by the way, is accessed on 68k macs by either some VIA
register twiddling, or by IIsi, PMU or CUDA style adb, so if you see any
refrences to that code anywhere, don't break it. :)


By the way, if you get rid of the nvram.c in drivers/macintosh, then it
would probably be fruitful to entirely disband the directory. I don't have
a 2.3 source tree handy, but I seem to recall that the 68k serial driver
was merged with the PPC serial driver a little bit back, and belongs most
sensibly in drivers/char anyways, adb probably belongs in a drivers/adb
directory so the NeXT port people need not associate with those icky macs
;), and after all that's gone there's not much of anything left in
drivers/macintosh that can't be moved elsewhere.


Cheers - Tony :)
