Suspending ThinkPad X220 upon closing the lid doesn't work on NetBSD 10.0

Hi everyone,

I'm running NetBSD 10.0 on my Thinkpad X220 and suspending my computer 
upon
closing the lid doesn't work. As I understand it, powerd(8) daemon 
listens to
such events and thus should suspend my computer. powerd(8) is set to YES 
in my
rc.conf. Furthermore, suspending the laptop with the sleep button works
perfectly fine, it just doesn't do it when the laptop lid is closed. In 
the
NetBSD Wiki there is a page for laptops, which describes, that 
Thinkpads, in
particular my Thinkpad X220 should be supported. I've read the powerd(8) 
man
page and there aren't any (for this usecase) important flags to set, so 
I'm
assuming just setting powerd to YES should suffice. The Guide even 
mentions,
that there is a script, which should be executed upon closing the lid, 
however
powerd just doesn't seem to call it.

What am I missing out on? Is there anything else I need in order for it 
to work?
