Well, I actually _think_ it works almost as-is on x86-64 too, but the 
magic is all in that small inline asm thing in <linux/resume-trace.h>.

The ".long" in that inline asm probably needs to be a ".quad" - see gow 
"generate_resume_trace()" uses it.

Also the "show_file_hash()" right now has a "tracedata += 6", and it 
should probably be "tracedata += 2 + sizeof(void *)" instead.

IOW, it really should be very easy to get to work on x86-64, I just 
haven't had the energy or inclination, since the only devices I've 
personally used it on have been regular 32-bit ones..
