In theory, yes it is sort of obsolete - sse and sse2 are the preferred
method. However, so long as you have specified -march=pentium4 (and
-mcpu=pentium4 or -mtune=pentium4 with >=gcc-3.4) mmx/sse/sse2 will be
implied as part of the compilation process.
As for mplayer - unless you set the appropriate use flag, then almost
all C(XX)FLAGS will be remove from the process as (like gaim) it is
notoriously flaky with anything other than the basic settings.
