Having spent a few months in Rwanda I must say it is incredibly hard to get a feeling of what's really going on as an outsider, because the topic is incredibly sensitive still. So whatever I'll say here is just the perspective I managed to piece together from various different accounts.

So, when Kagame liberated the country he made sure that both groups were represented in the Government. The president was a Hutu from his own party, and several other important positions were moderate Hutu's from either his or moderate parties, but even though Kagame was only minister of Defence during this period it is generally accepted that he has been the only one in power from the start. After the genocide there was a lot of hate left in the country, and despite Kagame trying to control the situation a lot of vengeance killings have been reported. In the first few years, there was also still a strong Hutu opposition to Kagama causing trouble, but they were pacified eventually (I'm don't know a lot about this period).

Currently, the country is one of the most peaceful countries around, and most Rwandese I spoke to state that there is no longer any ethnic tension since everybody is now considered Rwandese. This is not entirely true, however, and there is some tension below the surface. Most power and wealth is simply in the hands of the Tutsi minority, and I have noticed that ones background can be a determining factor when doing business. But it can't be stated enough that the government seems to do everything they can toward reconciliation, and bringing people together (a nice example is the concept of umuganda, where every last saturday everybody comes together in their community and first do a few hours of communal cleaning and than discuss the problems and issues they are facing together). Furthermore, although Kagame has since taken up the actual position of president, he is always careful to share important positions with the Hutu majority.

At the same time, everybody seems to be extremely happy with the current situation, for obvious reasons. The country is extremely peaceful, safe, corruption free and growing economically. They have come from very far in short period of time, and I think that almost everybody in the country realizes that they have it very well under Kagame, and therefore nobody seems to be eager to change the current situation.

The government is currently working on changing the constitution to extend Kagame's time in office, and although elections in Rwanda should not be considered entirely fair, I don't doubt that a majority of both groups desire the current stability an progress above uncertainty of new leadership.
