I spoke too soon - \ifpdf isn't a pdftex extension. From texinfo.tex:

\newif\ifpdf
\newif\ifpdfmakepagedest

% when pdftex is run in dvi mode, \pdfoutput is defined (so \pdfoutput=1
% can be set).  So we test for \relax and 0 as well as being undefined.
\ifx\pdfoutput\thisisundefined
\else
  \ifx\pdfoutput\relax
  \else
    \ifcase\pdfoutput
    \else
      \pdftrue
    \fi
  \fi
\fi

So same question for \pdfoutput. I see the memo says \pdfoutput
changes to \outputmode, so that seems good.
