I have also an X220. My experience differs a bit.

The machine:

FreeBSD X220.ovitrap.com 10.0-CURRENT FreeBSD 10.0-CURRENT #4: Thu Jun 21 14:29:15 WIT 2012

Both behaviours work. When I press the power button shortly, the machine shuts down. When I keep it pressed for a few seconds, the power is switched off.

Disk led works as expected.

The light seems to be switched by the hardware or BIOS  as it generates no event.

The keys for display brightness up and down also do not generate an event on my machine.

I did not notice this.
