After looking at what geometry does, it seems that it works like in dvips,
i.e., by writing a \special in the xdv file. Line 1016 of geometry.sty says

\AtBeginDvi{\special{papersize=\the\paperwidth,\the\paperheight}}

and, of course, you can set as you prefer the two parameters. If you
compile

\documentclass{amsart}
\usepackage{lipsum}
\paperwidth=10cm \paperheight=20cm
\textwidth=.8\paperwidth \textheight=.8\paperheight
\calclayout
\AtBeginDvi{\special{papersize=\the\paperwidth,\the\paperheight}}
\begin{document}
\lipsum[1-50]
\end{document}

(which exploits the \calclayout macro of amsart, just to avoid computing
parameters), you'll see that everything is OK. With amsart one can also 
use geometry, of course. With this package, \pdfpaperwidth and \pdfpaperheight
are defined to be the same as \paperwidth and \paperheight.

(Xe)LaTeX users would take care of non standard page sizes with geometry,
anyway. Plain TeX addicts should simply say

\special{papersize=<width>,<height>}
