Mario pointed me to

  http://www.columbia.edu/~em36/ubuntubreezythinkpadt42.html

which suggests that upgrades from Hoary -> Breezy (-> Dapper?) may leave
cruft around. In particular, some of the ACPI stuff seems different from
what other folks have reported.

In the case of Fn+F4 and Fn+F12, both generate events and they both
execute scripts of the form=20

#!/bin/bash
. /usr/share/acpi-support/key-constants
acpi_fakekey $KEY_SLEEP=20

The "acpi_fakekey" for sleep works. The one for hibernate does nothing.
Running /etc/acpi/hibernate.sh *does* seem to do the right thing.

I'll check on that too.
