The attached patch makes things better, by using real-but-unused
bytes in NVRAM instead of clobbering the clock chip.  Two issues
with the patch:

 - the "#if this is Linus's machine" thing can be improved on;

 - it's not clear if the three bytes used are available on many
   machines other than the one I tested this with.

Maybe the best way to do this is to give the PM_TRACE thing some
Kconfig options, where one would be to clobber the RTC and another
would clobber some configurable NVRAM bytes.
