Getting that support upstream would definitely be useful, so if you feel so inclined splitting out (or creating anew) the required patches ... I don't know how it's structured, but making the !SSE distinction runtime would be strongly preferred over any compile-time .config switchery. Otherwise, the guiding principle is that we'll do whatever it takes to support the hardware, with the reasonably best possible cleanliness.
