Isn't there's an option of selecting which file you want to move to SD in "Link2SD".
You should have an options of 3 choices to tick with.
1) Link application file
2) Link dalvik-cache file
3) Link library files(if app uses library files)
With above options you would be able to move all installed app's data plus its associates files to SDcard.
*still you need to partition your SDcard to have Link2SD to work. But this is the best move since app2sd is not user friendly(it running in the background without user controlable) and froyo wouldn't move all user installed app as one thought of... froyo only give certain apps privillage to move files which depending on apps developer requirements.
I have mine running froyo yet still having link2sd installed for more user control of which file to move where...
After all, your SDcard should also in larger size(8GB or 16GB) to enjoy the moving apps freedom..
