Check the docs. > 2.6.25.x. Upgrading X past what's currently packaged by the distribution > just to get a new kernel working is somewhat of a pain. Your X is broken, and in an extremely hideous way. You could try to get it to disable ACPI key support, or you can make sure nothing EVER sends ACPI video events to it. That means you must not use the ACPI video module in your kernel until you install a fixed X.org. -- "One disk to rule them all, One disk to find them.
