Yes, i was wrong, according to System information  only one driver is
enabled for each configuration (speed/stamina).

I don't know if two cards are a problem .... after switching to nVidia

 In my case, this intel related pci0:0:2:0 and pci0:0:2:1 are disappearing
completely in "speed" mode.

As for TPM, on my laptop BIOS at POST says that "No TPM or TPM problem",
I've used a little bit before Japanese version of SZ9 (or SZ8, It was not my
notebook, so I may be wrong), there was no such message there.
Theoretically, most of SZ models must have it (it's one of  features of SZ
series).

As I understand, BIOS is not capable (or not willing) to relocate resources
after booting till next booting.
So even in theory...

Need to learn a bit more ASL :)
