so, it's a running state.

how do i know "if it works?"

# sysctl hw.pci.do_power_nodriver
hw.pci.do_power_nodriver: 0
# sysctl hw.pci.do_power_nodriver=1
hw.pci.do_power_nodriver: 0 -> 1
# sysctl hw.pci.do_power_nodriver=2
hw.pci.do_power_nodriver: 1 -> 2
# sysctl hw.pci.do_power_nodriver=3
hw.pci.do_power_nodriver: 2 -> 3
