Its not just the system driver, there are quite a few issues :-

a. Lots of background services which are started by default.
b. Also the kenel as well as packages should behave in a manner which
make battery life longer. This is not the case at the present .

For e.g. http://forums.fedoraforum.org/showthread.php?s=84bfb8cd28895385bee083cc30eed476&p=1267038#post1267038

I'm sure there would be many more instances if one looked at it.

The use-cases are unique to laptops and laptops in battery-mode. Any
benefits on this are surely going to overlap with UNR as well. (as it
suffers from similar constraints)
