You can always shove a bunch of your textures into one big texture and 
do things that way.. it's worked pretty well for me, though the code is 
a little more convoluted.

Also, I forget which extension it is, but modern video cards support 
non-power-of-2 texture sizes.  Anything that supports Quartz Extreme in 
OS X this feature, so all newish Macs can be expected to support it... 
though you'll probably be competing pretty fiercely with WindowServer 
for texture memory on the older cards unless you're running full screen 
:)
