At least on the nvidia mux the power switch seems to be executed
by the ACPI PS0/PS3 methods so need to do it explicitly.

As I feared, whilst this fixed the clocks for the Lenovo U160, it broke
many other machines. So lets reverts commit 448f53a1

The IPS driver is designed to be able to run detached from i915 and
just not enable GPU turbo in that case, in order to avoid module
dependencies between the two drivers.  This means that we don't know
what the load order between the two is going to be, and we had
previously only supported IPS after (optionally) i915, but not i915
after IPS.  If the wrong order was chosen, you'd get no GPU turbo, and
something like half the possible graphics performance.

This patch tries to make sure that the vbl.reply.sequence
vblank count for a queued or emitted vblank event always
corresponds to the true vblank count of queueing/emission, so
the ddx can rely on the returned target_msc for consistency
checks and implementation of swap_intervals in glXSwapBuffers().

Without this there is a small race-condition between the
userspace ddx queueing a vblank event and the vblank
counter incrementing before the event gets queued in
the kernel.

Kconfig says fbcon is required by drm_kms_helper.  If radeon, fbcon,
and drm_kms_helper are all modules, radeon is auto loaded (by PCI id?),
drm_kms_helper is loaded because of the module dependency, but fbcon
isn't loaded leaving the console unusable.  Since fbcon is required
and there isn't an explicit module dependency, request the module
to be loaded from drm_kms_helper.

On resume, we were attemping to unblank the displays before the

waiting for things that are not yet programmed.  Re-program
