[A83] Re: Battery checking
Yes it does, but also there's very little fluctuation of the CPU speed due
to battery strength. I ran a test once and posted results on the TI-H list.
I can grab them if anyone's particularly interested, but they're not very
interesting :) I'm not hardware expert, but I'm guessing that the voltage
regulator would more or less kill this sort of endeavor. You never know
though...
