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?

As of 10.3.6, it is not: the 6800 Ultra's exported capabilities are identical to the 5200.

(On Windows, the 6800 exports ARB_texture_non_power_of_two and a few other useful extensions, like ARB_shading_language_100, ATI_draw_buffers, NV_float_buffer, NV_half_float...)

Re: the confusion between *_texture_rectangle and ARB_texture_non_power_of_two, this is clearly explained in the "How is a conventional NPOT target different from the texture rectangle target?" section of the spec: http://oss.sgi.com/projects/ogl-sample/registry/ARB/ texture_non_power_of_two.txt

EXT_texture_rectangle is available on anything newer than a Rage128. ARB_texture_non_power_of_two isn't available on any Mac renderer yet.
