I think it's pdftex's.

Maybe pdftex is yet fixed... We should try this out with a recent
pdftex, the one in Debian is rather old. If you don't want to do it
(it's probably some work to integrate it into Debian), you could send me
a copy of this pdf file, and I can try it out.

The encoding file and TeX font metrics are installed. Thus it's
perfectly possible to produce a dvi file containing the font, only the
printing or dvips/dvipdfm/ps2pdf conversion has to be done
elsewhere. I don't know whether upmap can do anything to fix pdftex,
while keeping it for tex.
