I tested this once upon a time... I think the cpuid entry I used was:

cpuid = [ '0:eax=0x3,ebx=0x0,ecx=0x0,edx=0x0',
 
'1:eax=0x06b1,ecx=xxxxxxxxxxx0000xx00xxx0000000xx0,edx=xxx00000xxxxxxx0x
xxxxxxxx0xxxxxx',
          '4:eax=0x3,ebx=0x0,ecx=0x0,edx=0x0',
          '0x80000000:eax=0x3,ebx=0x0,ecx=0x0,edx=0x0']

I tested it with XP and it worked but Silverlight wouldn't install
because it needs the SIMD instructions and they are turned off because
Intel and AMD have different implementations.
