I've a Mobility Radeon HD 5650 muxed with an intel card. If I boot with radeon.audio=1 and I switch the radeon card off when pulseaudio is running, then the kernel hangs as soon as I close X: [ 489.177732] hda-intel 0000:01:00.1: Disabling via VGA-switcheroo [ 489.297129] hda-intel 0000:01:00.1: Cannot lock devices!

Not sure if this is a pulseaudio issue or a kernel one (that should notify pulseaudio about the unplugged HDMI audio card).
