\Gm at checkdrivers is from geometry.sty, which contains the following test:

\def\Gm at checkdrivers{%
   \ifx\pdfpagewidth\@undefined\else
     \ifnum\pdfoutput=\@ne
       \Gm at setdriver{pdftex}%
     \fi
   \fi
  ...}

I contacted Hideo Umeki in late October and he agreed to change the 
pdftests to use the ifpdf package instead.

However, the real culprit is the cslatex.ini file in TL2005. It ends 
with the following bit of code:

\ifx\pdfoutput\undefined \else % added in Feb. 2005
    \catcode`\{=1  \catcode`\}=2
    \def\tmpa{\pdfcslatex}
    \expandafter\def\expandafter\tmpb\expandafter{\csname\jobname\endcsname}
    \ifx\tmpa\tmpb %% PDFTeX with PDF output
       \message {jobname=pdfcslatex, PDF output initialised.}
       \openin0=pdftexconfig.tex
       \ifeof0 \message{WARNING: pdftexconfig.tex does not exist.
                        I set \string\pdfoutput=1 only.}%
       \else \closein0 \input pdftexconfig.tex
       \fi
       \pdfoutput=1
    \else
       \message {jobname=cslatex with pdftex, DVI output initialised.}
       \pdfoutput=0
       \let\oripdfoutput=\pdfoutput \let\pdfoutput=\undefined
    \fi
    \let\tmpa=\undefined \let\tmpb=\undefined
    \catcode`\{=12
\fi

I don't see why this
   \let\oripdfoutput=\pdfoutput \let\pdfoutput=\undefined
is needed.

By comparison, the cslatex.ini file on my Mac (using gwTeX) starts out 
with this:

\ifx\pdfoutput\undefined
\else
   \ifx\pdfoutput\relax
   \else
     \input pdftexconfig
     \pdfoutput=0
   \fi
\fi
