Good news -- the Treo 90 syncs just fine with OS X over USB. I hard-deleted my previous version of Palm Desktop (which I had been using with my Visor) and installed the 4.0 available at Handspring. Perhaps overkill, but it worked. No need for MissingSync.
I'm quite relieved, because as of Dec 23 I found not a single confirmation that this was possible, only claims as late as Fall 2002 that it wasn't. The only encouraging post I saw was Rue's, and I wasn't positive it referred specifically to the 90.
Happy New Year!
