For S3, If you want to look at, you should start with this directory:

sys/amd64/acpica/
and compare with
sys/i386/acpica/

especilly with the acpi_wakeup.c code.  It may be possible though that
there are still some issues with the APIC code (which is kinda required
under AMD64), though this may be resolved already.

It's likely that porting the pmtimer device to the amd64
architecture is helpful for preserving time across a suspend/resume
sequence, but that can wait.

S4 is a different story.  There is one project at the moment, but no
code has been released yet.
