Definitely. And while I agree that the AU would be a better organization to take the lead in Sudan than the UN, that's not really a perfect solution either. For one thing, the AU simply doesn't have the resources to successfully intervene, nor do they have the authorization to do anything besides observing and defending themselves. And Darfur is not particularly high on the AU's priority list anyway - the situation in the DRC is a more significant crisis at the moment, and Zimbabwe and Somalia are both on the verge of crumbling into (even further) chaos any day now. The situation in Darfur is ongoing, yes, but it's not nearly as urgent today as it was in 2003 and 2004 (back when NATO action such as a no-fly zone would have actually been useful).
And to those who try to pin this all on European colonialism...again, it's not nearly that simple. Of all the crises in Africa, the one in Darfur (and now, increasingly, Chad) has perhaps the least to do with Europe. The way the French drew borders in the region didn't help ease tensions, but it didn't create them either. Sudan and Chad lie on a major cultural fault line between Arab Muslims in the north and Christian and animist black Africans in the south, and conflict between them goes back to the Arabs raiding the south to obtain slaves centuries before Europeans set foot in Africa. It's also been severely exacerbated by the Sahara's expansion and increasing water shortages in the region.
I go back and forth on what I think should be done in Darfur, but it's an extremely complex problem. Getting China to divest would help some, yes. But it wouldn't heal the thousand-year old problems faced in Sudan altogether. And it's also not going to happen - China and Sudan need each other too much. China already gets about 7% of their oil from Sudan if I'm not mistaken, and Sudan as a result has one of the fastest growing economies in Africa (and in the world).
So let's not oversimplify this too much. I'm certainly not opposed to helping in some way, but throwing money at the problem isn't the answer, especially in Africa where Western aid frequently fuels corruption and gives capital to a violent black market economy, or at the very least makes the recipient nations dependent on outside assistance and incapable of self-sufficiency. And as good as "increased awareness" would be, more people knowing about Darfur doesn't make the problem any simpler to solve. (And by the way, you must be hanging out with a lot of really stupid, uninformed people if they haven't heard of Sudan or Darfur - at my school EVERYONE knew about them, although only on a simplistic, naive, "blame-it-all-on-Western-imperialism" level).
