Regarding board changes.  It is probably quite common for manufacturers
to change the physical board
designs in products.

I know (have seen with my own two eyes) that there were at least two
totally different versions (in terms of
layout of chips etc) of 520/1040STf(m) motherboards -- and I've heard of
at least one more version.  The
two boards were totally different - RAM and ROM location, CPU location, etc.

I doubt Atari changed the Mega 2 layout to purposely cripple it.  That
makes no sense at all.  The Mega 2
layout was probably changed to fix something, to make use of different
but functionally same parts, or to
decrease manufacturing costs.
