I can't speak for the 16MB question.  However, I have used a RamKeeper 
for years, with a GSRAM+ card, 4MB RAM.  The CDA does allow you to 
allocate arbitrary amounts of the card for regular RAM, and 
for the battery-backed RAM disk (/AEROM).  I was able to boot ProDOS or 
System 5 (didn't have Sys6 at the time) off this disk.  What I don't 
remember is how the memory address space looked with such an arrangement.

Incidentally, I haven't used the AERamKeeper in a while, and would be 
willing to let somebody have it for $25 + shipping.  Let me know.
