You are correct to a degree but the cards have to be the same, different brand of cards e.g. an XFX 8800GT and an EVGA 8800GT can be SLi'd if they are both G90 or G92.
iirc you may also be correct about the different speeds e.g. a G92 GT and a G92 GTX can be SLi'd which is where the GTX would be reduced to the GT performance level.
8800GTS + 7600GT, no way, sorry.
