Yep. It was Andrew Trigdell (with friends) who reverse engineered some of those magic numbers in the first place, and even I never knew what were they good for.

Personaly I think that running without ACPI today is no longer an option, especially on laptops. So I would indeed go in this direction.

Unfortunately, this is something I always wanted to do and never get around to. I don't have such a list, I only have a rather big mail folder containing sony related mail. I don't remember if I already said this, but I think it would be a good idea to start a wiki to create some sort of documentation. > I suggest that the goal might be to have a single consolidated > sony-laptop driver.
