Hey ToniCipriani!
I just found where the plugin preference gets enabled!!
/var/luna/preferences/systemprefs.db
flashplugins|false <- (or true, depending on what you set on 2.0)
I only copied the libflashplugin.so to the correct place, and "enabled" it per the 2.0 browser preferences card, but I don't get anything.
I don't know how much you did copy from the 2.0 browser, but could you try opening the systemprefsdb and create that entry?
palm-webos-device / # sqlite3 ./luna/preferences/systemprefs.db
sqlite> insert into Preferences VALUES ("flashplugins","true");
sqlite> .quit
This should enable the plugin the same way it gets enabled on a 2.0 device, or at least enables the setting on the preferences, we still have to see if it works
