The same happens on my Latitude D430 (which also worked fine under Hardy).

Bryce, /proc/acpi/event is busy because acpid is already connected to it. Stop it, then you can cat it:

$ sudo /etc/init.d/acpid stop
 * Stopping ACPI services... [ OK ]
$ sudo cat /proc/acpi/event
button/power PBTN 00000080 00000001

If I press Fn+F1 (hibernate) or Fn+F3 (battery status), nothing happens. If I press the power button, I get the output above.
