Comment:

 I took a look at the linux kernel sources for the values put into
 /proc/cpuinfo (arch/x86/kernel/cpu/proc.c), and I don't see any sse3, only
 ssse3 (there is sse4 related flags, though). It *looks* like the real name
 of sse3 is pni:

 I committed the changes in r4931 and r4933 (has_sse3 returns true when pni
 is detected, a function has_ssse3, and detected nocona if both has_sse3
 and !has_ssse3() are true). I think this should fix the issue for good.
