I've just noticed: GCC's docs say
    winchip-c6
          IDT Winchip C6 CPU, dealt in same way as i486 with additional
          MMX instruction set support.
    winchip2
          IDT Winchip2 CPU, dealt in same way as i486 with additional
          MMX and 3dNOW!  instruction set support.
so I don't think we should use -march=i586 as a fallback.

There's also c3, which has 3DNow, but not SSE.

    c3
          Via C3 CPU with MMX and 3dNOW! instruction set support.  (No
          scheduling is implemented for this chip.)

    c3-2
          Via C3-2 CPU with MMX and SSE instruction set support.  (No
          scheduling is implemented for this chip.)

I'll try to send a patch this weekend.
