The actual current draw I did not measure -- I was looking for voltage sags or 
swells on the +5V and +12V lines during load.

yes it's a simple find but there would be significant disk/cache thrashing 
when combined with a kernel complile, as I'd mentioned.

Yes I completely agree with you here.

I am willing to bet that my case is the more general case here -- The TDM 
current draw just is not a big draw, or at least it should not be -- 
certainly no more than a HDD during heavy seeking or a video card during some 
intense gaming sequences or even some of the larger data acquisition/DSP 
cards I've used in the past.
