jaeezzy was wondering about a battery indicator for this project (LXDE as replacement desktop). I managed to get something working using battery-status (deb) and gxmessage (included in Easy Debian).

I made a little script that displays the battery percentage as a dialogue box; I'll try to package it up as a deb this weekend.

basically, you put the battery script on the little maemo menu and you click the battery button when you want to know the status of the battery.
