[POWERPC] powermac: Suspend to disk on G5
Powermac G5 suspend to disk implementation. The code is platform agnostic but only tested on powermac, no other 64-bit powerpc machines. Because nvidiafb still breaks suspend I have marked it EXPERIMENTAL on powermac and because I can't test it and some lowlevel code will need changes it is BROKEN on all other 64-bit platforms.
