For power - I suspect it's damn near irrelevant except on a big big machine.
Unless you've sorted out your SATA, fixed your phy handling, optimised your desktop for wakeups and worked down the big wakeup causes one by one it's turd polishing.
PM means fixing the stack top to bottom, and its a whackamole game, each one you fix you find the next. You have to sort the entire stack from desktop apps to kernel.
However benchmarks talk - so lets have some benchmarks ... on a laptop.
