I agree with most of what everone has added to this thread, and I wanted to point out again that z/VM, while it's a nice product to have, is just way too expensive and quite unnecessary to use for just a small number of z/Linux LPARs. I think that most existing z/800 and z/890 processor complexes probably already have been delivered with an IFL, and not to use it by running a z/Linux LPAR is really a waste. I also agree that if you have to pay for one now, that a Zaap is a pretty good deal and can pay for itself if you aren't going to run a z/Linux LPAR. But the IFL is great otherwise.
Additionally, I have successfully configured multiple non-IBM servers that were previously running Linux and Windows to run the same workload on a z/Linux LPAR and the performance has always been much better. Obviously the hardware reliability is always better on the mainframe, and the cost (without z/VM) is almost non-existent (again, assuming you already have the IFL sitting there).
