Hi Evan! Sorry for taking so long before answering... Thanks for the greps! It appears you have a newer version of apple_gmux than I have, so let's see if something also changed in the _DSM method. Could you please run - as root - `acpidump -b -n DSDT` which will create a file named dsdt.dat containing the DSDT table, and then run `iasl -d dsdt.dat` and send me the resulting dsdt.dsl file? That way I will have the uuid, the available functions and their version for your _DSM method.
Regarding bringing the clocks down, you could add a fake performance level in the vbios but I'm not sure if it would be a good move. You should rather power off the NVidia card and only use the Intel one - using vgaswitcheroo, see [1]; once I have that dsdt.dsl file, I should be able to add support for auto-powering down the NVidia card. Or you could try to motivate some developers - or if you want to give it a try - to investigate / add support for power and/or clock gating.
