Well, I've taken the easy way out and simply used ditched ACPI, and used APM support, which works just fine on IBM Thinkpads. It would be nice if ACPI worked, and every so often I put in a day or two worth of futile frustration trying to improve ACPI support on my T40 laptop, but with so many things being broken, and my only having limited number of hours in the day, so it was much easier to simply fall back ten yards and punt. This is not a particularly satisfing solution for people who are stuck with Dell or Sony laptops that don't have APM support, and who only have ACPI, but this might have something to do with why I know a lot of kernel developers who use IBM Thinkpads. :-P - Ted P.S.
