I'd be VERY careful about changing the voltage to the device.  You don't 
know what its tolerance is going to be.  Also, just raising the supply 
voltage is not going to help you if your incoming power is dirty.  It is 
still going to spike / droop / etc on you - just at a higher voltage now.

That will also be a useful experiment.

I can't speak to how this thing sucks down power.  There isn't anything 
going on in the driver to try to manage the power consumption of the 
device.

I'm on IRC right now.  To get my attention be sure to put my handle 
"mcisely" in the message - gaim will see that and generate a much more 
annoying sound effect :-)
