 (I'm answering for Thad, as he's running around the country at the
moment)

 Thad and I are both running one of the SuperMOPS boards (586dx133),
with 2.1 Gig HDD, PE and twiddler. Running full out (ie, compiling
kernel), the system draws about an amp, and is running at 5 volts from
a DC-to-DC converter. When idle, consumption drops to about half an amp.
 Using two of the LI+ NP-950s (~32 W/hr each), we're getting about 12-15
hours on day-to-day useage, which means we're running a lot closer to
5 watts than 2.5. Hmmm, some of this is probably due to lossage in the 
power converter, because those are only about 80-85% efficient. The newer
ones look substantially better. 
 Regardless, battery life of 12 hours or more is really nice...
