With pstricks-add you can divide everything by 1000 and use xlabelFactor and
ylabelFactor. The only problem is that you have to use showorigin=false,
otherwise you get "0000" at the origin. Maybe Herbert has a fix for that?

\documentclass{article}

\usepackage{pstricks-add}

\begin{document}

\begin{psgraph}[arrows=->,Dx=250,Dy=50,xlabelFactor={000},ylabelFactor={000}
,
  showorigin=false](0,0)(1500,160){11.2cm}{6.4cm}
% Functions
\psplot[showpoints=true,plotpoints=15]{0}{1500}{0.08615 x mul 18 add}
\psplot[showpoints=true,dotstyle=square*,plotpoints=15]{0}{1500}{0.05468 x
mul 42 add}
% Captions
\rput[l](1000,70){\psline(0,2)(100,2)\psdot(50,2)\qquad\quad graph one}
\rput[l](1000,50){\psline(0,2)(100,2)\psdot[dotstyle=square*](50,2)\qquad\qu
ad graph two}
\end{psgraph}

\vspace{1cm}
\psset{unit=.00008mm,xunit=.00008mm,yunit=.0004mm}

\begin{pspicture}(0,0)(1500000,160000)
