Work-around for Lenovo T530:

The host has dual video adapters: an Intel integrated low-power and an NVidia discrete high-performance.
The host has a special (AFAIK Windows-Only) mode with both video adapters running (one one stand-by) to be toggled by the OS. The mode is called 'NVidia Optimus' in the BIOS settings.
With 'NVidia Optimus' the kernel crashes (or blanks-out).
With 'Integrated' the kernel boots (and chooses i915 driver).
With 'Discrete' the kernel boots (and chooses whatever nouveau/nv/nvidia is available).

So for the work-around: choose to use the Discrete OR the Integrated video adapter.
