Ok, the following works:
    \special{papersize=\the\paperwidth,\the\paperheight}

It puts (for \setuppapersize[letter][letter]) the following into the DVI 
file (dvips -d3 test2.dvi 2>&1 |grep special):
papersize=614.295pt,794.96999pt  which gv shows as letter.
Having the right unit (as defined in page-lay.tex, i.e. 148mm×210mm for 
A5, 8.5in×11in for letter etc.) would be probably better, but this works.

That expands to:
   papersize=\paperwidth ,\paperheight
which dvips cannot digest.

Whereas that expands to

papersize=\begingroup \scratchdimen \paperwidth \relax \scratchdimen 
0.0351459804\scratchdimen 0.0cm\endgroup ,\begingroup \scratchdimen 
\paperheight \relax \scratchdimen 0.0351459804\scratchdimen 0.0cm\endgroup
<cmr12.pfb>[1Processing special: papersize=\begingroup \scratchdimen 
\paperwidth \relax \scratchdimen 0.0351459804\scratchdimen 
0.0cm\endgroup ,\begingroup \scratchdimen \paperheight \relax 
\scratchdimen 0.0351459804\scratchdimen 0.0cm\endgroup

still something dvips cannot digest.

I have to admit, I actually fail to expand
   \special{papersize=\PtToCm{\the\paperwidth},\PtToCm{\the\paperheight}}
correctly. It always ends up as \begingroup ... in the DVI file (i.e. as 
above with \paperheight|weight replaced by its numerical value).
