You need the following as root:
Try stopping acpid
/etc/init.d/acpid stop
and then
cat /proc/acpi/event
This is where acpid gets its acpi events from. Now try pressing your power
button (you can also check your lid button just in case to make sure). If you
are not getting a message from the power button then for some reason the kernel
is not generating the messages, probably an acpi or a dsdt problem. If it worked
in 2.6.8 I am guessing an acpi bug though.
