Change subject: [WIP] Nvidia Optimus support for ThinkPads
......................................................................
Patch Set 7:
Just some additional information if someone finds it useful:
nvidia proprietary driver won't work unless the _ROM method is implemented. This is true even for qemu/kvm guest to which you can pass the pci-rom argument. That is sufficient for nouveau though.

I think I know why it doesn't work. PCI ID of my dGPU is 10de:0ffc, which can be checked with `lspci -nn`. But the ROM I extracted from vendor UEFI dump is for 10de:0ffb, which can be checked with `romheaders` and there's also "ID mismatch: vendor ID 10de, device ID 0ffb" error line in cbmem. I'll try to edit the device ID in the ROM image.
