 yeah.  wild, huh? :)

 yes.  this is why the leemote all ends up at about 10-12 watts.  it's
all too much.  an AM3892 with say 1gb of 1600mhz DDR3 RAM would be the
kind of insane beefy little system i'd like to propose.

 holy cow, i didn't realise the AM3892 actually has 64-bit DDR3 RAM
interface (2 32-bit).  that would explain why it's 1,000 pins, apart
from anything.  oo, it can do 2gb as well.  wow.   hmmm.... can we
actually _get_ 8 RAM ICs as well as the CPU and a couple of NANDs into
75x45mm? :)
