I am not sure if setpci is normally available on OSX or it was installed by lspci, but it's working fine so far and I have all the ASPM capabilities turned on.

The script has to be edited according to their position (it is very well commented) and launched at startup.

This package provides the HP 3D DriveGuard software for supported notebook models that are running a supported operating system. I found this to be the case in my Hackbook: i installed lspci (I found it by googling 'lspci osx') and found out that the RTL8101E ethernet card in my laptop only had the L0s mode enabled by default, and the corresponding PCIe root complex wasn't enabling that either, while the AR9285 was enabling L1 only and ASPM for the root complex was again disabled.
Building a CustoMac Hackintosh: Buyer's Guideįor some time there has been a problem with laptops running Linux that some BIOSes wouldn't enable PCI Express power saving features ("Active State Power Management" or ASPM) for certain wireless cards, substantially reducing battery life.
