	I don't think that it is a pain at all. My belief is that it is just the 
way that the VPC hardware is set up ( I may be wrong on that, but I HAVE tried 
many ACPI calls to find one which makes one of the cards vanish completely, 
and drew a blank. )

	The fact is that with the call that I use in my hack of your module, the 
power consumption falls in a way that is consistent with disabling the NVidia 
card, even though it still appears on the PCI bus, further evidenced by the 
fact that hda-intel driver fails to wake up the HDMI audio chip from D3.... so 
as I said I don't think that is an issue at all.
