I think it is not as useful as it was before.
Status for NVIDIA Optimus: the nouveau driver has improved runtime PM
(enabled by default for Optimus laptops). IIRC, that landed in Linux
3.12. In comparison with bbswitch, it improves co-operation with
HDMI audio. From time[1] to time[2], new laptops are released that
turn out to be incompatible[3]. These DSDT dumps are then useful to
debug those issues, but nobody seems to care about the dumps posted
here.
AMD hybrid graphics: I have not heard much about this. The open-source
radeon driver is supposed to save power too through vgaswitcheroo,
I do not know if the power saving is also implemented through runtime PM.
