Caution--if you use the non-power-of-two extension, you lose some
functionality (like texture wrapping, I believe). Also UV coordinates
are specified differently (pixel-based instead of zero-to-one based).

I believe that an update to OpenGL (1.5?) has eliminated the

Mac-OpenGL could better answer this?
There is an extension (ARB_texture_non_power_of_two) which lifts the
restriction, and OpenGL 2.0 requires the presence of this extension.
It is not, however, supported on all cards. AFAIK, the GeForce 6
family are the only hardware currently able to support this extension.
Can one of the lucky few who have received their GeForce 6800 Ultra
DDL cards confirm whether the extension is supported on Mac OS X?
