Neanderthal rights?

Ronald Bailey looks at the ethical questions that will pop up when Neanderthal Man is cloned.
Once the Neanderthal genome is complete, could it then be used to clone an actual Neanderthal? Harvard University biologist George Church thinks so. He told The New York Times that a Neanderthal could be brought to life using present technology for about $30 million.
A good rule of thumb:  If something can be done, sooner or later, it will be done. Then what?
Will Neanderthals be considered human?
What rights would they have? One way to approach the question is to ask if Neanderthals would be able to make and keep moral commitments. One significant clue that they might have this ability is the fact their genomes have the same version of the FOXP2 gene that we do. Our variant of that gene is necessary for articulate speech. The human (both modern and Neanderthal) FOXP2 gene differs from that found in chimps and most other primates by two changes in its genetic sequence. The fact that Neanderthals carried the same version means that it is possible that they could talk and might have been able to make and keep promises. If Neanderthals had this ability it strongly suggests that they would merit the same moral consideration that we give to our fellow human beings. If they can speak, there's a good chance that they can also demand rights.
Archaeological evidence also indicates that Neanderthals behaved in ways similar to modern humans. They controlled fire, wore clothing, made and used tools, and buried their dead. In addition, they physically developed in much the same way as we do. Like modern humans, Neanderthal infants were born with relatively large brains and took a long time to mature into adults. Some researchers believe that modern humans and Neanderthals could interbreed. Does the future hold inter-species nuptials?
....

So what if we bring back Neanderthals and it turns out that their intellectual capacities are so dissimilar from ours that they cannot cope successfully with modern life? Should we control their fertility so that they go extinct again? This comes uncomfortably close to the eugenic arguments used to justify sterilizing people who were deemed mentally defective in the 20th century. Or perhaps Neanderthals could be placed in reservations where they would be allowed to develop without further interference from modern humans. Would this be akin to confining them to a zoo?

And indeed, if their intellectual capacities are that much lower than ours, would they become a slave class?  One of the justifications for slavery in the American South was that blacks were inferior and needed to be managed for their own good.  How much more tempting to make that case when it's actually true?
We may stand on principle and refuse to create an underclass, but I can imagine a rich dictator thinking the creation of a permanent slave class would be just the thing for his empire.
Anything that can be done will be done.
By someone.
