If something came out that was AMD64 Generation 2 specific (and wasn't supported by regular AMD64), it'd have a USE flag that only works on AMD64. And you wouldn't want to turn that flag on on a normal AMD64, since it doesn't support it.
Right now, if you compile mplayer, you'll get MMX/SSE/SSE2/3DNOW and all that crap. Just there are no special USE flags for it.

I thought that if you 'cat /proc/cpuinfo' it'll show you the flags
that are compatible with your cpu. Is that not accurate for the amd64
chip?
