What I finally figured out was that "-march=native is *EXTREMELY*
conservative". As a matter, I started a new thread on exactly that
topic<G>. To summarize... "-march=native" had disabled mmx, sse, sse2,
sse3 (aka pni), and ssse3, all of which are available on the cpu. After
explicitly adding those flags to CFLAGS, emerging system+world, and
rebuilding the kernel, it runs 1080p just fine, thank you.
