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.  Interesting.

cheers, Ian
