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
OpenCL platform 1: AMD Accelerated Parallel Processing, 1 device(s).
Using device 0: Intel(R) Core(TM)2 Duo CPU     P8600  @ 2.40GHz

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)
        Device version:         OpenCL 1.2 AMD-APP (923.1)
        Driver version:         2.0 (sse2,avx,fma4)
        Global Memory:          7966 MB
        Global Memory Cache:    16 KB
        Local Memory:           32 KB (Global)
        Max clock (MHz) :       1400
        Max Work Group Size:    1024
        Parallel compute cores: 8

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).

****Please see 'opencl_bf_std.h' for device specific optimizations****
