I seem to recall that we tried pushing hard on TI to up
the memory capacity of the mX, but there's a hard physical
limit of 12Mb in the on-board addressing.  To change this
they'd have had to remask the big ASIC they have and they
didn't fancy doing it.  At the time, I believe, they were
so impressed with the performance of their TGC that they
really thought that people would not want more physical
memory (ha).

Sorry, no idea.

I don't recall any significant changes between the two,
but then that was quite a while back.

So how might I get to 12 MB? Swap chips on the board?
