Thanks for the quick reply!

When you said they didn't offer any assistance, do you mean assistance
with testing?  If so, how about if the support is trimmed out for the
newly-added chips that have no available test system volunteers, and
then slowly add those back as people make test systems and testing
time available.  Should I presume that you have access to one or more
systems with the added ITnnnn chips?  I volunteer my system for
testing the IT8686E support.
