 Definitely -- that's a nice board.  I've noticed it's not going to work 
reliably in any memory slot but the last one on the KN03 baseboard -- 
there is a small IC (a PAL?) next to it -- perhaps it provides support 
specifically for the NVRAM board.  I don't know if it's true for the KN02 
board as well.
