i suppose that in pdftex.ch in the lines

if (pdf_h_origin =3D 0) and (pdf_v_origin =3D 0) then begin
    pdf_h_origin :=3D (one_hundred_inch + 50) div 100;
    pdf_v_origin :=3D (one_hundred_inch + 50) div 100;

the (pdf_h/v_origin =3D 0) was planned to check whether pdf_h/v_origin
have already been set. And this might interfere with the user setting
\pdfhorigin=3D0pt. So maybe one could try to add two boolean variables
like pdf_h/v_origin_set, and check these instead of the pdf_h/v_origin
values. Not yet tried, just a guess.
