Not really. :(  There's an apple-specific extension for it.  On
the other hand, YUV->RGB conversion should be really
easy to write as a fragment program (either NV_texture_shader,
ARB_fragment_shader [GLSL], ARB_fragment_program,
NV_fragment_program) on any gf3-era card or later, which I'm
guessing is why not many implementors are rushing to standardise
YUV textures.
