Speaking of which, right now smart_kernel_intel() doesn't disable the
S3 hooks. I think with KMS, we shouldn't need to run any video hooks.
So, perhaps something like this should be added:

local kms=`cat /sys/module/i915/parameters/modeset 2>/dev/null`
[ "$kms" = 1 ] && remove_parameters --quirk-s3-mode --quirk-s3-bios
