Pursuant to GPL, they even let you download source: http://www.tivo.com/linux/linux.asp
I have a ReplayTV personally, which I love. Yeah, they never really did have the impact as a company in the UK that they did here. Of course, here, the slow agonizing death thing is sort of happening in a different way.
All kinds of devices, including many routers, run Linux or similar kernals efficiently. But you have to compare OS X to something else that has OS X's versatility. OS X does pretty well for itself compared to most of those things. You can't do nearly as many things on a TiVo box as you can on an iBook. That robustness can carry a cost, because you have to provide many different programs with different ways to do different things.
Now in the case of these computers, I hope that MIT and company are very frugal and make them work really well, really efficiently / snappily, and make them do what they do in a straightforward manner, much more à la TiVo than à la any desktop OS, Linux distros included.
