How can I enable the power button on my server?

The power button on my headless 11.10 server appears to do nothing unless I hold it in for 5 seconds or so, in which case it switches the machine off instantly.

What I'd like it to do if I press it briefly is a normal shutdown (shutdown -P now). How can I allow this?

I have seen this question but it is for desktop installations.
