If you are willing to waste some memory, you can always set up your  
texture coordinates to only include the region of the power-of-two  
texture that has sprite data.  Or, as you say, use NPOT textures.   
Although they're only now becoming part of the standard, they are  
usable via extensions of a wide range of hardware.
