I reported that partial success back. To get that into Jaunty I need to come up with a patch that only matches specific laptops. Can you post me the output from your "sudo demidecode", please?

For the strange behavior of the keys: Was this happening before as well or only with the never kernels? I cannot say for sure, but there is another problem in these acpi bios definitions, which is that the spec says brightness level definitions contain two special values at the beginning. The brighness for ac and battery mode. The definitions for this laptop do not have these values and immediately enumerate the brightness levels.
