This is a known problem and i am deliberately not adding such features
(whitelisting based on PCI IDs etc) to s2ram since i also believe that there
should be only one place for the whitelist and it seems that most people think
that this place is HAL.

Nobody proposed to use the s2ram whitelist, just the "mechanics" that it provides.

BTW: it would probably be pretty trivial to make s2ram invoke tuxonice if
somebody showed me the spec (a.k.a. "what do i need to do to invoke suspend to
ram with tuxonice) instead of invoking the normal in-kernel suspend.
