Comment 247 for bug 95444

The sony scripts were dropped from acpi-support because based on testing, these events were believed to now be handled in the kernel input layer. If your brightness hotkeys on sony work when you downgrade to the intrepid version of acpi-support, but stop working when upgrading to the jaunty version, then please open a new bug report against acpi-support with information about your model and include the output of both 'showkeys' and 'acpi_listen' when pressing these keys.

If it's a bug, it's an entirely separate bug from the one this bug report is about, so closing the acpi-support task.
