I was working on suspend/resume support for amd64 and this is the 
result.  It works with a modified QEMU (QEMU does not support S3) but 
real boxes that I have don't seem to like it (e.g., broken BIOSes).  
If there is someone interested in finishing it off or giving it a 
try, the patch is here:

Please note this patch is heavily inspired by Takanori Watanabe's SMP 
patch for i386:

and large portion is shamlessly stolen from Peter Wemm's AP boot code 
for amd64. ;-)
