Hmm, I don't think I can help much but I have been following the ACPI
issue for a new laptop of mine, < 1year. I don't know how IBM supports
ACPI in older laptops, maybe APM works better, less functions though.
My education so far is the ACPI in the latest 2.6 kernels works pretty
well, it is the userland tools that can report all the data in a nice
GUI interface is what I haven't found. I have had to resort to the
command line to get/set parameters, but I don't use KDE or Gnome
(WMaker) which may have more utilities in this area.
