Hi Adam,

I actually patched my BIOS. But this is really just a *single* byte
different from my original Bios (checked with hex-diff :)
--> why not (I can put back my old bios anytime --> no real warranty
issues either).

Now I have the choice and with "STATIC" I can choose before power-on. So
far I only use STAMINA which makes the nvidia effectively disappear
(lspci wise and power consumption wise).

But if I choose "Auto" for the VGA Switching Policy (which is the
setting for the unpatched BIOS): The intel card works just the same!
Only you lspci shows also the nvidia. At this point I did not try yet to
turn off nvidia with NP kernel module. But I will dig further at some
point :) ...  For now my priority is getting the power-management down
to about 10W and the FN keys to work without the deprecated kernel
option CONFIG_PROC_ACPI_EVENT(s).

And waiting a while without too many Xorg user programs (like firefox,
...) running I can get <10W :)
