I am experiencing something very similar on my macbook core2 duo, using feisty. Everything was good but after the 17th of February update Ubuntu does not detect my machine as a laptop.
What is happening:
1. gnome-power-preferences just show me AC power tab options.
2. battery charge monitor applet loads and show correct battery status but says it is using Legacy (non hal) backend.
3. cat /proc/acpi/battery/BAT0/state and info seems pretty good.
so it seems that hal does not detect battery and everyone that just can use hal behave according to this fact.

How may I check why hal is misbehaving?
