In GL 2.0 it's a core feature. So if you detect a 2.0 compatible driver you'll have it. Otherwise check if the GL_ARB_texture_non_power_of_two extension is supported.

To get the list of extensions supported by your hardware and OpenGL version call glGetString (http://www.opengl.org/sdk/docs/man/xhtml/glGetString.xml).

You can also look for GL_ARB_texture_rectangle which allow to load NPOT textures but in a more limited way: no mipmaps, no normalized texture coordinates, some wrapping modes unsupported, etc...
