There seem to be significant differences though. Most changes are  
related to color, but others are related to graphical manipulations  
such as rotation and scaling.

For example /usr/local/teTeX/share/texmf.tetex/tex/latex/dvipdfm/ 
dvipdfm.def (which is the latest version of dvipdfm.def) includes:

> \def\Grot at start{%
>   \special{ps: gsave currentpoint currentpoint translate
>   \Grot at angle\space neg rotate neg exch neg exch translate}}
> \def\Grot at end{\special{ps: currentpoint grestore moveto}}
> \def\Gscale at start{\special{ps: gsave currentpoint currentpoint  
> translate
>   \Gscale at x\space\Gscale at y\space scale neg exch neg exch translate}}
> \def\Gscale at end{\special{ps: currentpoint grestore moveto}}

while dvipdfmx.def includes:

> \def\Grot at start{%
>   \special{pdf:btrans rotate \Grot at angle}}
> \def\Grot at end{\special{pdf:etrans}}
> \def\Gscale at start{%
>   \special{pdf:btrans xscale \Gscale at x\space yscale \Gscale at y}}
> \def\Gscale at end{\special{pdf:etrans}}

As an additional nicety, the obsolete dvipdfm.def shipped in the  
graphics package of the latest LaTeX release even includes another  
variant:

> \def\Grot at start{%
>   \special{pdf: bt rotate \Grot at angle\space }}
> \def\Grot at end{\special{pdf: et}}
> \def\Gscale at start{\special{pdf: bt xscale \Gscale at x\space yscale  
> \Gscale at y}}
> \def\Gscale at end{\special{pdf: et}}

I'm curious which of these will work with XeTeX on Linux.
