There is no 65nm GPU for the XBOX 360 yet.

All HDMI XBOX 360s are either 'Zephyr' motherboard (as first seen in the Elite) with 90nm CPU and GPU, or the 'Falcon' motherboard (with 65nm CPU and 90nm GPU, as seen in newer Elites and Premium/Pros, and most probably in the new Arcade).

The 65nm GPU boards ('Jasper') are not due out until August 2008:

I expect that support will also continue for Linksys products - this seems to me to be an exercise in marketing efficiency, rather than promoting two separate brands and the marketing dollars required for both, they just have to promote one brand to reach customers across all sectors.
