There is a special ID, maybe it can be used but i'm not sure if its

I found out some places in acpi memory that are different when the card
is really enable but.. honestly i've no idea what they're for yet ;)
The led switching is fine using GFX0, and it seems enabling stamina is
fine as well, but enabling nvidia does not work very properly.
additionally, when the nvidia is *really* enabled, switching to stamina
gives a black screen (i'm not sure how telling the console to use the
intel card works, or is supposed to work).

Can you post somewhere (or anyone else) a acpidump of a Z11 that has
hybrid video switching working? I'd like to compare the acpi tables with
mines (and with the module code) and see if i can figure out things quicker.

Thanks
