That sounds very plausible.

It's probably a fairly simple bug - I expect there just needs to be an extra calculation somewhere in the implementation of the \pdf*pos primitives to take account of the offsets - but I'm afraid I don't have free time at this point to investigate exactly what needs fixing. Perhaps one of the other people who've hacked on xetex code will be able to take a look.

It ought to be possible to work around the issue at the macro level by avoiding the use of \hoffset/\voffset; it's not essential to manipulate these in order to implement cropmarks (though of course it may be convenient). Perhaps using the geometry package instead might work better, if it implements things in a different way?
