Nice, I've been waiting for this for a while.  Well, sorta waiting.  It 
turns out that the battery life on my Acer Pentium M laptop is so good 
that I can estimate when it'll run out mentally.  "Has it been more than 2 
hours since I wandered away from an outlet?  Hm, maybe I should return."

Now I just have to wait for this to be MFC'd to RELENG_6. :)
