Content of /proc/cpuinfo for Opteron 146, socket 939.

Description of problem:
File /proc/cpuinfo only displays SSE related flags sse and sse2 for an Opteron 146, socket 939. I believe that no stepping earlier than E4 was available for socket 939. Thus I would expect sse3 to be supported,too.

Version-Release number of selected component (if applicable):
kernel-2.6.29-0.67.rc8.git4.fc10.x86_64

How reproducible:
Always.

Steps to Reproduce:
1. Cat /proc/cpuinfo.
  
Actual results:
Capabilities sse and sse2 are reported.

Expected results:
Flag sse3 is returned, too.

Additional info:
Utility x86info actually reports the processor being an "Opteron/Athlon 64/Athlon 64 FX (SH-E4)", and feature flags also includes sse3.

sse3 is called pni in linux for historical reasons.
