OK ... I'll look again.  The only doc I have for this is a 1998 HIM
guide for the u160 chip, so it's possible earlier versions didn't
support the >12 CDBs but I'd expect a field warning in that case and I
don't see one.

Chances are there's simply another issue in the driver that I haven't
seen yet.
