Just s2ram.  Handling quirks in s2ram and in 99video was just annoying,
but with the recent "interesting" behaviour of the nvidia g80/g90 chips
and their habit of only coming back from suspend if you posted from a
saved copy of the BIOS, s2ram was causing resume failures that 99video
handles correctly, so the old "disable 99video in favor of handling the
quirks in uswsusp" bahaviour missed this case when running with s2ram.

While I suppose I could set up some sort of framework where certian
quirks are handled by s2ram and certian others are handled by 99video,
that seems like a recipie for disaster.  

s2disk and s2both are still supported by this patch series, and now we
force s2both to run quirkless.  I could have s2ram do the same thing,
but since all it ends up doing the same as what we already do, it is
just as easy to fall back to the kernel method.
