I'm starting to get this too now, but I've deliberately not updated to 10.6.7 following the recent postings on the XeTeX mailing list.

For me, it happens only in reduced size, as in a text-style fraction.
Full size characters show just fine, and similar documents have worked fine previously.
Maybe it is just a font caching thing?

There are 100,000s of PDFs in archives, having similar embedded subsetted fonts.
If some PDF reading software has recently changed, then this is a regression that needs to be reversed.
