Bug Description

Nouveau can be disabled in linux-aws, and must be disabled in order to disable some ACPI features.

Colin King has demonstrated measurable boot speed improvements (up to 3%)
by disabling many ACPI features not used by cloud kernels. That work also
allows us to unhook additional unused subsystems (Nouveau, gpiolib, pincntrl).
Disk space utilization of the kernel is reduced:
  /boot by ~200KB
  /lib/modules by ~170 Kb
