Make sure the power supply is actually powering the NSLU2 before you
measure it (the voltage may drop under load).
The NSLU2 power supplies are notoriously bad, and nearly all reports of
dead hardware have turned out to be because the power supply has failed.
I have seen people reporting that if you plug a powered USB hub into the
NSLU2, the shoddy USB wiring in the NSLU2 will let you power it from the
hub without needing a real power supply it all. If you have one, that
might be worth trying. No promises, though.

If you have problems with your NSLU2 booting up properly, there might be several reasons (including corrupted nonvolatile memory), but power supply is probably most common. Checking the 5V power supply without load does not always help in locating the problem. Power supplies with bad electrolytic capacitors may drop in voltage under load, while appearing "okay" with nothing else connected than the voltage meter.
Also, it could be helpful to check the NSLU2 PCB for discoloration from heat, or visibly "blown" electrolytic capacitors, too.
