Many vendors lately put 2 video cards in laptops. The switch is triggered by an ACPI method afaik. The linux module taking care of that is called vga_switcheroo.;a=blob;f=drivers/gpu/vga/vga_switcheroo.c

It shouldn't be that hard to support, and it is specified how to do in the ACPI spec. It's quite low on my todo-list, but anyone who knows the basics of driver writing could do this if they want to start with ACPI.

My Sony Vaio Z11 has this also. But first it has to show to the Haiku bootloader.

Last I heard the Nvidia/intel scheme was completely different to the Radeon/Intel scheme?

Mine is Nvidia/Intel so work on that first please ;)
