ACK. This is an important distinction to make.

The current limitation is pdftex, which can have it's default papersize
changed only by changing pdftexconfig.tex and redumping all formats. The
different pdftexconfig.tex files needed for a4 and letter are hardcoded
into texconfig.

How about having the original files in TEXMFDIST and change texconfig
such, that it writes the new files to TEXMF(SYS)VAR? That way the user
will not have to deal with the files. But if needed, these files can be
overruled by a file in TEXMF(SYS)CONFIG. One problem that I see right
now is what texconfig(-sys) should do when such a file exists in

dvipdfm allready links against libpaper. For dvips I currently see no
possibility to have one configuration file specify another one, that
should also be read.
