Are you sure acpi_ibm is actually doing the connect? What do you see
for 'sysctl dev.acpi_ibm'? You should see a list of items, many of
which will be '0', even though they should not be. Things like
'fan_speed'. Setting dev.acpi_ibm.0.mute or dev.acpi_ibm.0.thiklight
to '1' should work.

I think the  hotkeys should default to 2484.
