Btw is it correct that it is not possible to load detect with this hardware on DVI-I when nothing is connected? (Comes up as connector status unknown).

It should work. Sounds like you were testing without the proper quirk patch in place or it was being called on the wrong encoder. See atombios_dac_load_detect() and radeon_atom_dac_detect() in atombios_encoders.c.
