First let me say that I only have the RamFAST Rev. D manual and that I don't 
own a RamFAST card of any revision.  So I didn't personally run any those 
tests.  Any of the testing performed was with the GS-RAM Plus card maxed out 
to 6 Megs tested in several IIgs machines with the respective GAL installed. 
The manual I have notes if you have a GS-RAM Plus card and it's a revision A 
then DMA must be disabled.  My card is a revision D which I lent for testing 
so that could help explain why there weren't any issues.

I'd love to retest the card maxed out to 8 Megs but I can't seem to find the 
2 Meg Expander.  If/when anyone does come forward with the 2 Meg Expander 
then I'll rerun my tests and see if my results change.
