After PyFFI'ing the vanilla meshes you should pack them into a .BSA without compression, rename the file to the default file (Oblivion - Meshes.bsa), change the modified date to that of the original file, and replace the original file after backing it up.
When I did it I unpacked the entire original .BSA, moved the files to the toaster\in directory, right-clicked oblivion_optimize.ini, and clicked Run PyFFI. Then I used OBMM to create a new .BSA, added the in directory, added the out directory, and packed it into an uncompressed .BSA. I then used SetFileDate to set the date modified to January 29, 2006 18:53:40.
The configuration for PyFFI will skip all the files it needs to automatically, including .egm files.
