I'm not sure if a new driver is required but after emailing the reporter of https://launchpad.net/distros/ubuntu/+bug/33855 he suggested that it fixes the problem described in this bug and more accurately described https://launchpad.net/distros/ubuntu/+source/acpi-support/+bug/31525
The actual problem is twofold.
1) acpi hotkeys only work once! That is one keypress per shutdown-restart cycle. After that nothing. 2) When they do work (occasionally) the only ones that actually do anthing are the brightness up/down key
