Basically, what it does is to make swsusp avoid saving (and restoring)
non-RAM pages (like the ISA hole, BIOS etc.).  I think it is a nice thing
to do and it does not hurt anyone (it only clears and/or sets PG_nosave
at some places).  However, if we decide to do this for i386, it should
also be done for x86-64.

Greetings,
Rafael
