	More oddness in my quest to get both graphics cards working on the VPC-Z 
WITHOUT modding the BIOS or booting an old kernel first....

	If I use sony-laptop--zseries-0.9np7 to switch to stamina mode at boot 
time, I get a load of:

hda-intel: spurious response 0x0:0x0, last cmd=0x0f0000
	
	on the console... followed by "no codecs installed." This doesn't happen 
if I boot the old kernel to statically switch to stamina mode.

	I'm guessing that I must be missing an acpi call or something, though why 
switching GPU statically or via ACPI makes a difference I really don't know.

Adam.
