I wasn't clear, sorry, and misinterpreted what you wrote.

After systematic testing:

\documentclass{article}

  -> A4: TeX + dvips + gs
  -> A4: pdfTeX
  -> A4: XeTeX
  -> A4: LuaTeX

\documentclass{article}
\usepackage{graphics}

  -> A4: TeX + dvips + gs
  -> Letter: pdfTeX
  -> A4: XeTeX
  -> Letter: LuaTeX

\documentclass[a4paper]{article}

  -> A4: TeX + dvips + gs
  -> A4: pdfTeX
  -> A4: XeTeX
  -> A4: LuaTeX

\documentclass[a4paper]{article}
\usepackage{graphics}

  -> A4: TeX + dvips + gs
  -> A4: pdfTeX
  -> A4: XeTeX
  -> A4: LuaTeX

OK, I'll adapt my practice to this.

But I'm surprised: I thought the idea was a total separation between

- the media size, based on \pageheight etc., defined in pdftexconfig.tex and the like, on one hand;

- the page size (used for calculating the text width and the margins etc.), based on \paperheight and the like, defined by the package option, on the other hand.

As I said, no big deal, I'll adapt.
