	yes, i understand your problem.  i don't mean to change this list into a
	physics lecture, so unless i have this wrong, let this be the end.

At the risk of being shot ...

Ohm's law (E = I/R) only works for linear resistances.
The argument being put here (I think) is that this DIMM is a non-linear
device which requires a fixed amount of power.

This is a bit like a circuit with a voltage regulator (for all I know, the
DIMM has one) or some types of UPS.  If the input voltage drops, the device
will draw more current in order to maintain the output voltage.

I promise to say not another word on this :-)
