I don’t have time to do it tonight, but the best way to debug if this is a XeTeX problem or a package problem (never underestimate the ability for fontspec to do something it shouldn’t) is to load the font using “plain TeX” font loading; something like:

    \font\xx=“[abc.otf]/OT:+ss01” at 10pt
    \xx ABC123

Hopefully that’s enough to get started…

Cheers,
Will
