Please get a crash dump with matching kernel.debug and acpi_video.ko.debug.
Then grab and source it while running kgdb.
You can use the 'kldload' command to generate output that you can pass to
asf(8) to generate a file you can source to import the symbols into kgdb
for the kernel module.  Then you can get a stack trace which will help
track down the problem.
