Well, which ones?  If you're asking about the new framework, it's been there
since 2.6.29 and is a recommended way of implementing PM hooks now.

Please have a look at Documentation/power/pci.txt. :-)

I'm not 100% sure it fixes everything yet, although I hasn't been able to
reproduce the problem with it applied, so far.

So, I don't think it's -stable material at this point.  However, it should be
done anyway at one point, so it very well can be done right now, given that I
have the hardware to test it. :-)

Thanks,
Rafael
