apm on amd64 (FreeBSD 12.1)

[Dirk-Willem van Gulik]

After a recent upgrade to 12.1 release - I noticed that rc.d/apm is 
specific to i386; and cannot be enabled on amd64.

Does that mean that AMD64 laptops no longer need APM for good power 
management* ? Any man-page or 'updating' notes one can study to understand ?

*) As prior; enabling it on an Thinkpad X270 appeared to make the 
battery last a lot longer during lengthy suspends.
