If I read correctly, this module allows you to check battery temp? How do you actually check it and I have a play around and see if I can work anything out. E: nope, that didn't work. Will contact jay-c and see what he says.
modprobe bq27x00_battery
AFAIK bq27x00 is conflicting with BME. If you load the module in bootup, BME won't start most of the time, and the system reboots. We had this problem with Nitdroid, but it is solved now with a more advanced bq27x00 module. However, it is safe to load the module once the system is up and running (!?!)
