The best thing would certainly be to contact the author and describe 
briefly the problem in case he's not aware of it. And if the author is 
no longer maintaining the package, you might also look at the newsgroup 
comp.text.tex.

I can't be of much help, as I'm not using geometry.sty myself. Looking 
briefly at the code, it looks so intricate and so sophisticated that 
I'm not sure anybody but the original author can fix things properly.

You may try putting in your preamble, without any guarantee at all, 
based on the \AtBeginDocument code inside geometry.sty:

\makeatletter
\AtBeginDocument{%
   \ifGm at pass\else
     \ifnum\mag=1000\else
       \ifx\pdfoutput\undefined\else
         \divide\pdfpagewidth1000
         \multiply\pdfpagewidth\the\mag
         \divide\pdfpageheight1000
         \multiply\pdfpageheight\the\mag
         \divide\pdfhorigin1000
         \multiply\pdfhorigin\the\mag
         \divide\pdfvorigin1000
         \multiply\pdfvorigin\the\mag
       \fi
     \fi
   \fi}
\makeatother
