Investigate patches that moblin may have (AndyWhitcroft)
Make the populate_rootfs() call happen in parallel with the rest of the kernel startup (AndyWhitcroft)
- i915 drm driver takes 1.5s to init on its own
Investigate patches that moblin may have (AndyWhitcroft)
and remove need to load i915 from the initramfs (ScottJamesRemnant)
Clean up initramfs console setting (ScottJamesRemnant)
