Here comes a new challenger!

Same deal as Optimus: A GPU wired through an IGP. No mux.

First laptops featuring this seem to be the Dell Vostro 3550 (6630M) the 
HP dv6/dv7 (6490M?/6770M). The BACON driver situation for Sandy+Radeon 
on Windows is currently being documented and there have been some 
switching problems for the HP laptops.

On the AMD+Radeon side of things, almost nothing is known about BACON. 
An upcoming Llano laptop (1 of 11) from HP is apparently going to be a 
beast. A 6750M+6520G Hybrid Crossfire and dynamically switching laptop.

Current fglrx support for PowerXpress, radeon, or vga_switcheroo are 
said not to work in enabling the discrete GPU for any meaningful use.

Given this, there will be a need for data collection tools and possibly 
new scripts (call it BaconBits or extend Bumblebee).
