On a Thinkpad X270.

When configuring /etc/powerd/scripts/lid_switch like indicated in https://www.netbsd.org/docs/guide/en/chap-power.html#chap-power-ex-powerd-lid_switch, closing the lid makes the system go to sleep, but have difficulties to get back on re-opening.

When closing the lid everything looks fine, the LED goes to sleep after a few seconds.
Reopening the lid, you are greeted by a fixed cursor on a black screen for like a minute.
When at last your Desktop is back, the laptop track-pad and keyboard are unresponsive.

The system is indeed back from sleep, you can regain control of it by plugin in a USB mouse and keyboard.
However the track-pad and keyboard are basically dead.

That allowed me to get the console log:

So the culprit here is the PS/2 driver that connects the track-pad and keyboard, is there a way to detach it so we can put in the lid-close script to do so before going to sleep, then re-attach when waking-up? 

Tried the following trick to no avail:
drvctl -Q pckbcN        # keyboard controller
drvctl -Q pckbdN        # PC keyboard
drvctl -Q pmsN          # PS/2 mouse


Also, after wake-up the system can show some kind of freezes, typing in a terminal a command like ifconfig takes a few seconds to complete.

Related output of drvctl -lt
