I tried with the latest sources in the luatex/branches/experimental.
All of 1.eps, 2.eps, and 3.eps have the same
%%BoundingBox: 2 -9 45 -2
%%HiResBoundingBox: 2.09999 -8.90779 44.85638 -2.09999

#!/bin/sh
mpost test.mp
mv test.eps 1.eps
rm test.log test.mpx
#
mpost -tex=tex test.mp
mv test.eps 2.eps
rm test.log test.mpx
#
mpost -tex=etex test.mp
mv test.eps 3.eps
rm test.log test.mpx

Best,
