To report possible bugs in pdfTeX you DON'T cry wolf everywhere.

- \pdfhorigin (dimension) 
This parameter can be used to set the horizontal offset the
output box from the top left corner of the page. A value of 1
inch corresponds to the normal TeX offset.  This parameter is
read when pdfTeX starts shipping out a page to the pdf output. 

For standard purposes, this parameter should always be kept at 1
true inch. If you want to shift text on the page, use TeX's own
\hoffset primitive. To avoid surprises, after global
magnification has been changed by the \mag primitive, the
\pdfhorigin parameter should still be 1 true inch, e. g. by
typing \pdfhorigin=1 true in after issuing the \mag command. Or,
you can preadjust the \pdfhorigin value before typing \mag, so
that its value after the \mag command ends up at 1 true inch
again. 

- \pdfvorigin (dimension) 
This parameter is the vertical companion of \pdfhorigin, and the
notes above regarding \mag and true dimensions apply. Also keep
in mind that the TeX coordinate system starts in the top left
corner (downward), while pdf coordinates start at the bottom left
corner (upward).
