I don't understand.  The i-RAM takes normal RAM.  If you're swapping
then that normal RAM is best put in your motherboard as normal RAM,
not in some funky RAM-as-SATA device to use as swap.

No one is suggesting using i-RAM as direct memory, and indeed that
would be bizarre since i-RAM converts normal RAM into a disk
device which you then access over SATA.
