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