not sure if this will help and it's not magical...but
i found this registry hklm\software\tegic\et9\ime with a key named MdbFile that points to HTCMDB.txt in the windows dierctory. it is a list of words...perhaps before you flash a new rom, navigate to that registry level with the registry editor and export the IME structure.

after the new flash is done, you can double-click on the .reg file saved during the export function and it will import it. i'd recommend turning off HTC sense before double-clicking.

hope this helps...
