The current Mesa GLX module does already support MMX and 3DNow:

./configure --help
[...]
  --with-mesa-version     specify the version of MesaLib to be used
                          (mesa30, mesa31) [autodetected] 
  --with-x86-asm          use x86 assembler instructions [autodetected] 
  --with-mmx-asm          use MMX assembler instructions [autodetected] 
  --with-3dnow-asm        use 3DNow! assembler instructions [autodetected] 
  --with-chipset          specify the chipset for hardware acceleration
                          (mga, tnt) [mga]
