from what i can see, identcpu.c fetches the cpu name using a cpuid
instruction.

my system with dual 1.1ghz durons identifies as:

CPU: AMD Duron(tm) MP Processor (1110.94-MHz 686-class CPU)
  Origin = "AuthenticAMD"  Id = 0x670  Stepping = 0

Features=0x383fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,
CMOV,PAT,PSE36,MMX,FXSR,SSE>
  AMD Features=0xc0440000<<b18>,AMIE,DSP,3DNow!>

the entire "AMD Duron(tm) MP Processor" string appears to originate from the
cpu, so i would suggest that the processor is named duron mp.  the ident
string does not change when booting a non-smp kernel, so unless the cpu is
detecting the chipset as dual cpu or the bios is reprogramming the cpu, that
is actually what amd have named the 1.0+ghz durons.
