Yes.
This allows you to use the richness of the  ps-backend,

There is no good  pdf  driver, either for  dvipdf
or  pdftex  directly. This is because  PDF  is not
programmable to anything like the extent that PostScript is.
There are structures that Xy-pic uses with PS that cannot
be handled by PDF, so using PS as an intermediary is a good
way to get the best quality.

Indeed, my recommendation is to use either of the
  {pdftricks} or {ps4pdf}  packages.
These (in different ways) enable you to make PDF
images of the diagrams, then import the images back
into your LaTeX document.

Kris, remember years ago that we discussed this strategy,
thinking about programming it into Xy-pic ?
We dropped that idea, as being too generic!
Given that the functionality existed already, we had
no compelling need to duplicate it.

  ... as it would, since the PostScript \special commands were
not designed to work with PDF.

However, if you aren't using a back-end, but just font characters,
then I don't know what would be going wrong.
Would you post an example please?
--- include both the coding and the output, and also the .log file.
