it is not a pstricks problem. You have to pay attention for
inserted spaces from LaTeX:

\documentclass[portrait, a0b]{a0poster}
\usepackage{pstricks,calc}

\begin{document}

\psframebox{%  <=== !!!!
\begin{minipage}[c][10cm][c]{\textwidth-2\pslinewidth}

text

\end{minipage}%  <=== !!!!
}

\psframebox[framesep=0cm]{%  <=== !!!!
\begin{minipage}[c][10cm][c]{\textwidth-2\pslinewidth}

text

\end{minipage}%  <=== !!!!
}

\begin{pspicture}(0,0)(\textwidth,10cm)

\psframe[linecolor=red](0,0)(\textwidth, 10cm )

\end{pspicture}

\end{document}
