SMBus (system management bus) is a physical communication bus which lives in your computer, whether you have a smart battery or not.

to dissassemble your DSDT dmesg or lspci are useless. you need to cat /proc/acpi/dsdt and use iasl to dissassemble the output file. look in the gentoo forum, there is a very good tutorial there.

Usually, I plug it into AC power. if that's impossible, 2 things can happen:
if I have an idea of how long the battery has left... i use it for 3/4 of my estimated time, just to be safe.
if I have no idea of how much power the battery has left, I won't use it.

it's not that you can't get it working... it's just that nobody else has written a driver yet. probably smart batteries are not the most widely used batteries...
I am learning and gathering information to start coding, but I don't have enough time to do so in the next few months. also some other people on this list are doing the same. lmsensors people have 
some 2.4 work... but not enough to make it useful.

pedro venda.
