I just realised I have AMD SDK installed too %-)
Platform #1 name: AMD Accelerated Parallel Processing
Platform version: OpenCL 1.1 AMD-APP (831.4)
Device #0 name: Intel(R) Core(TM)2 Duo CPU P8600 @ 2.40GHz
Device vendor: GenuineIntel
Device type: CPU (LE)
Device version: OpenCL 1.1 AMD-APP (831.4)
Driver version: 2.0
Global Memory: 3846 MB
Global Memory Cache: 32 KB
Local Memory: 32 KB (Global)
Max clock (MHz) : 2401
Max Work Group Size: 1024
Parallel compute cores: 2
This is the one only supporting CPU. I have no problems running
bf-opencl with it (and it is faster than on Intel's SDK):
magnum@...ge:~/src/john/src [1.7.9-jumbo-6-fixes]$ ../run/john -plat=1
-t -fo:bf-opencl

Bull has this:
Platform #1 name: AMD Accelerated Parallel Processing
Platform version: OpenCL 1.2 AMD-APP (923.1)
Device #1 name: AMD FX(tm)-8120 Eight-Core Processor
Device vendor: AuthenticAMD
Device type: CPU (LE)

I too get the self-test fail on bull:
magnum@...l:src [1.7.9-jumbo-6-fixes]$ ../run/john -t -pla=1 -dev=1
-fo:bf-opencl
OpenCL platform 1: AMD Accelerated Parallel Processing, 2 device(s).
