Meh,
To me the problem with Heimdall's casting has little to do with 'race', has it has to do with 'respecting' the source material.
I remember coming out of Thor, and while the actor who played Heimdall did a fantastic job, while talking about the movie with friends, I said something along the line of, 'I like how they manage to make everybody look exactly like in the comic...' And then I had to correct with, 'Well, except Heimdall'. Now if me saying that a black man doesn't look like a white character is being racist... well, I guess I am, but I don't think that really qualifies.
Because no matter how good of a job he did, nothing will change the fact that he doesn't look like the character... while Thor, Odin, Loki, the Warrior Three and Sif all looked the part to a T (Well, Volstagg wasn't fat enough, but even so, he was easily identifiable).
Is it a big deal? No, not really. The movie was good and Heimdall was a scene stealer. But it's still something that can't be denied.
It's the same thing as if they had casted a blond guy to play Wolverine, or a black haired actress to play Mary Jane Watson (and hadn't dyed their hair, basically just going with it) - that doesn't mean the movie wouldn't be good. That doesn't mean the actor wouldn't do a kick ass job... but nothing would change the fact that Wolverine isn't blond and MJ isn't a black haired woman.
