is there really no way to have Xinerama AND all GPU's active mining like here described?

if Xinerama is on and I use 2 Monitors there is only one GPU active for mining
bfgminer and cgminer says
CL Platform 0 vendor: Advanced Micro Devices, Inc.
[2013-09-08 20:08:53] CL Platform 0 name: AMD Accelerated Parallel Processing
[2013-09-08 20:08:53] CL Platform 0 version: OpenCL 1.2 AMD-APP (1307.1)
[2013-09-08 20:08:53] Platform 0 devices: 1
[2013-09-08 20:08:53] 0 Cypress
[2013-09-08 20:08:53] ADL found more devices than opencl!
[2013-09-08 20:08:53] There is possibly at least one GPU that doesn't support OpenCL
[2013-09-08 20:08:53] Use the gpu map feature to reliably map OpenCL to ADL
[2013-09-08 20:08:53] WARNING: Number of OpenCL and ADL devices did not match!
[2013-09-08 20:08:53] Hardware monitoring may NOT match up with devices!
[2013-09-08 20:08:53] GPU 0 ATI Radeon HD 5800 Series hardware monitoring enabled
[2013-09-08 20:08:53] 1 GPU devices max detected
if Xinerama is off two GPU's are active for mining but I have only clone desktop on both Monitors
TIA
