  Well, first to address why Atari didn't put a 68040 in the TT.  First, 
the original TT was based around a 68020, however, Atari realized that it
would be hopelessly outdated by the time it got to market.  So, Atari took
the gamble that the 68030 would be available in mass quantities when they
got the TT to market.  The 68040, however, is still not available in large
quantities from Motorola and is extremely backlogged.  So, right now the
68040 is not feasible.  Think about it, if Atari was wrong, David Small 
would not be messing with a 68030 board, he would go 68040.
  Okay, here I am a little shaky... I wouldn't imagine that the 68040 would
be difficult to implement in terms of an upgrade, apprently Atari got TOS
into a state where it is hardware independant (thus the increase in size).
Therefore, I would think the 68040 would have no problems...

Just my humble opinion....
