I've been doing that too (after reading your original post).
I only posted about the restart issue because even after resaving the PDFs in compatibility mode, several of them were still not shown correctly until I restarted the Kindle and that information was not posted on the thread. Hopefully it will help someone in the future...
Anyway, the compatibility save seems to be reliable so far. I already processed about 50-60 files and none had any problems. Not an ideal solution, but for my particular files I guess I won't have any problems for missing features of "higher" Acrobat versions.
