Bumblee on Lenovo Ideapad Y570

Following the added support by the Nouveau driversfor the GPU in the Lenovo Ideapa Y570, Nvidia has recently added the 0DEB PCI ID (10DE:0DEB) to their drivers.
This means this laptop model is now supported by Bumblebee/Ironhide, and one can use the dicrete Nvidia graphics card on specified applications by installing Bumblebee/Ironhide under Linux.
This is for a NVIDIA GeForce GT 555M 1GB card, which has been seen on a bunch of different laptop albeit with slightly different names.

There are almost a dozen 555M GPU variants available. Every single one uses a GF106 chip with DDR3 or GDDR5 except for the Lenovo Ideapad Y570 which has a GF108 chip with GDDR5.

The 500M series has been a bit of a chipset mess for Nvidia. Some Dell users found ways to BIOS mod their GF108 525M into a 550M, but it's not an easy task.

As an example, the Asus G53SW/G73SW has a GF106 460M with a 192-bit bus and GDDR5. The supposed successor, the Asus G53SX, has a GF116 560M with a 128-bit bus and GDDR5. Yet at the same time, G74SX, the successor of the G73SW, has a GF116 560M with the expected 192-bit GDDR5.
