I'll report a failure on a TurionX2 laptop:
CPU: AMD Turion(tm) 64 X2 Mobile Technology TL-50 (1607.33-MHz K8-class CPU)
  Origin = "AuthenticAMD"  Id = 0x40f82  Stepping = 2
  AMD Features=0xea500800<SYSCALL,NX,MMX+,FFXSR,RDTSCP,LM,3DNow!+,3DNow!>
  AMD Features2=0x1f<LAHF,CMP,SVM,ExtAPIC,CR8>
  Cores per package: 2

Loading k8temp gives:
Feb 11 05:32:41 claus kernel: k8temp0: <AMD K8 Thermal Sensors> on hostb3
Feb 11 05:32:41 claus kernel: k8temp0: can't clear config registerdevice_attach: k8temp0 attach returned 6

Please excuse any delays as the result of my ISP's inability to implement
an MTA that is either RFC2821-compliant or matches their claimed behaviour.
