Comment # 18 on bug 71930 from Mike Lothian

With runpm=1 on adg5f's drm-fixes-3.12-radeon-poweroff which is based on
3.11.0-rc7 I get the following in switcheroo

0:DIS: :DynOff:0000:01:00.0
1:IGD:+:Pwr:0000:00:02.0

It also lists providers and DRI_PRIME works great powering the card as and when
I fire something up and shows this in switcheroo
