Flint,
DJ emailed me a heads-up question on this a few minutes ago and I was able to catch my local FSDO contact. If the manufacturer doesn't have those charts available, they suggest you contact your local FSDO office and explain the problem. They may be able to help out.
Personal opinion.. You may be able to talk them into an exemption for up to 180 days while you bug the ******* out of the manufacturer to get the charts done or the FAA certification office comes up with something.
If you don't know the location or number of your FSDO office, check the following url:
http://www.faa.gov/fsdo/
That's the national locator page for the FAA's FSDO offices.
