The 750ms delay is from thinkpad-acpi. I sent a patch to Henrique which
makes it go away, but I'm not entirely sure what the ACPI method
concerned is supposed to be doing. The opregion code won't currently run
until X is started because the drm layer requires X to be the foreground
vt before handling IRQs.
