Any suggestions? http://www.thinkwiki.org/wiki/Tp_smapi has a table of which Thinkpad models support what tp_smapi features. It's not clear to me whether any of this is exposed through ACPI tables, or whether it's all more direct hardware access .. sounds like a fun project if anyone has the time and energy to play with it though :) Thanls for the earlier references.
