p@pandora-test ~> sysctl -d hw.pci.do_power_nodriver
hw.pci.do_power_nodriver: Place a function into D3 state when no
driver attaches to it.  0 means
disable.  1 means conservatively place devices into D3 state.  2 means
agressively place devices into D3 state.  3 means put absolutely everything
in D3 state.
