I'm not familiar with the drivers, but I think that the independent
xetex.def is definitely needed.
I think that images png, jpg, pdf, are efficiently embedded in XeTeX,
probably by using primitives, while dvipdfmx requires an external
program extractbb to obtain sizes of the images.
% xelatex test.tex (xetex.def)
is far faster than
% xelatex test.tex (dvipdfmx.def)
