Hi David,
Linux is not very good at detecting the parallel port type and
will only catch up to Windows when PNPBIOS will be integrated
to 2.4.x.
I wrote a little tool "lssuperio" to help to identify issues
with superio chipsets. For your type I don't have yet infos !
You can help by downloading
http://home.t-online.de/home/gunther.mayer/lssuperio-0.63.tar.gz
and sending me the output of "lssio -x" if you like.
Regards, Gunther
