Your problem was
\step[\value{step}=1][\value{step}=2]{...}
which is better written
\step[][\value{step}<3]{...}

However, you can make your code much easier by using \steponce and \restep.
Does this do what you want? (I removed the star on \stepwise to make step 
1 actually be step 1, but you may of course add it if you want.)

\documentclass [a4paper]{article}
\usepackage{pstricks}
\usepackage[lightbackground,display]{texpower}

\begin{document}
\stepwise{
  \begin{pspicture}(0,0)(9,9)
      \rput(0.0, 8){A -- always }
      \rput(4,5){B -- always }
      \step[][\value{step}<3]{%
        \rput(2., 6.5){C -- in step 1 and 2} }

      \steponce{%
        \rput(5.5, 6.5){E -- in step 2}
      }

      \restep{%
        \rput(11,5){D -- in step 2 and 3}
      }

      \step{%
        \rput(7.5,8){F -- in step 3}
        \rput(4,8){G -- in step 3}
        \rput(5.75,6.5){H -- in step 3}
        \rput(9.25,6.5){I -- in step 3}
      }
  \end{pspicture}
} % End of stepwise
\end{document}

Best regards,
Hans
