I have an IBM Thinkpad T30. I have your exact same situation. 
acpi=on, enable gnome's battstat applet, shows as 0%, plus it seems 
to be polling something, which causes a slight, but noticable, 
slowdown. Anyone know why this doesn't seem to work correctly with 
Thinkpads? anyway, I just returned to using apm mode. Works well 
enough since my RH9 usage.
