Austin: We probably shouldn't assume your problem is caused by ACPI or that it's at all related to the backlight issue without more evidence. I've updated the bug description accordingly.
First I'd suggest testing whether the computer has really hung or if the display just isn't coming up. Try pinging the device on the network or logging in via ssh when the machine is in this state. If you determine the machine really has hung, please try the steps in the following link to see if they provide any information about where the hang is occurring and post your results here.
