To get a better feel for when / how this happens, can you let me know what is effected (display power / brightness controls / crash when closing lid etc..) if you remove the "video" ACPI module:
sudo rmmod video

This may identify if the bug is in the driver / BIOS, or can be avoided. If this avoids the crash, we've learned a lot. If it still crashes, we may have learn't a little.

Can you report the output of:
cat /proc/acpi/video/*/DOS

(Before and after removing the video module)

Can you run:
sudo cat /proc/acpi/dsdt > ~/dsdt.aml

and attach the dsdt.aml file created in your home-dir. (It _might_ be useful to take a look at the ACPI firmware from one or more affected machines.)
