You are absolutely right :) It is a specification which can be
implemented by a hardware. I think the hardware which supports ACPI is
mostly i386, x86_64, and ia64.
Also you can see that from drivers/acpi/Kconfig that linux acpi depends
on above mentioned hardware.

menuconfig ACPI
bool "ACPI (Advanced Configuration and Power Interface) Support"
depends on !IA64_HP_SIM
depends on IA64 || X86
depends on PCI
depends on PM

I am not an expert in PM area. But may be this will be helpful:
