Peter Wemm 5915fb72fb Prototype (but functional) Linux-ish /dev/nvram interface to the extra
114 bytes of cmos ram in the PC clock chip.  The big difference between
this and the Linux version is that we do not recalculate the checksums
for bytes 16..31.

We use this at work when cloning identical machines - we can copy the
bios settings as well.  Reading /dev/nvram gives 114 bytes of data but
you can seek/read/write whichever bytes you like.

Yes, this is a "foot, gun, fire!" type of device.
