Not quite.  The software checks if all banks of ram are SCRAM, and if so
turns on the mode.  Don't mix types.

Correct.  Read those numbers.

Yes indeed.  4Mb parts work perfectly (but kinda expensive if you actually need
to pay for them).  I'm sure I have seen some Sharp parts kicking about
somewhere.

100ns rams are required, but 80ns will also work.
