 yes that's the plan.

 yehhss... but you now need a CPU which can _take_ those DIMMs,
gordan.  it's worth double-checking, but i think you might find that
the bus (data) width on DIMMS is 2 to 4x what ARM CPUs can handle.
DIMMs are designed to be attached directly to the northbridge
[whatever] IC on an x86 motherboard.

  the reason why i mentioned those RAM prices is because at
mass-volume levels, when you subtract the cost of the DIMM PCB itself
you end up with a price that's staggeringly low.
