	Apparently it went in to acpi-test a couple of weeks ago. Thanks to Adam 
Williamson at the Fedora Project for pointing me at that one!

	Yep.

	The hda-intel module is the one responsible - it actually covers a number 
of different manufacturers of Intel HD Audio compatible hardware. The NVidia 
card in the VPC-Z uses one to generate audio on the HDMI port. The problem is 
that because when the NVidia related hardware is disabled it still appears on 
the bus, the driver still finds the HDMI audio chip on a probe. The PCI code 
which changes the power state of the chip realises that it hasn't woken up 
from D3 power state but does not return an error, so the kernel module has no 
idea that it is turned off. My patch simply causes the kernel pci code to 
return an error if the power state doesn't change. I've put the patch in my 
files directory.

Adam.
