[-- Attachment #1 --] -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I think it doesn't really make sense to by default use MACHINE_CPU=i486 when the kernel is built with SSE by default today. Attached patch uses i686 SSE MMX by default, the user can always change the default setting by overriding CPUTYPE (they have to do it as SSE is enabled by default for several years).
