The reason drow don't have racial feats is because, like all playable pc's in the MM they just didn't have room to write up propoer racial progressions for all of them. And they are not missing that much IMO, from what I gather racial feats are cool but not game breaking. So drow will get racial feats, probably in the FR book.
Also, you could custom make at least one racial feat, which allows drow to gain both their encounter powers instead of choosing one.
Lastly, while I don't have my books yet and while DV is quite an advantage, IMO its very circumstantial. The eladrin teleportation appears to me to be more useful. (I mean, it would be nearly impossibel to capture/bind/imprison the eladrin.
