The design for the LUCAS 32 bit memory board sounds good.  In my opinion,
having the extra memory autoconfig is probably not desirable if it adds
alot to the complexity of the hardware (an addmem like utility is fine 
and would allow us to easily disable the 32 bit wide RAM if necessary).

Although I will almost certainly buy the 32 bit wide memory board, I 
wonder if a cache board isn't more in keeping with the LUCAS philosophy.
Basically, it wouldn't require as many expensive memory chips and would
still allow a reasonable speedup.  As I am not a hardware expert, perhaps
I'm missing an important reason why this would be unrealistic (perhaps
the design would be too complex or too many exotic parts would be required).
