I had an NVIDIA card in this computer and I installed the nvidia-opencl-dev package with no issues. After installing the ATI card, I tried to install the boinc-amd-opencl package and it tells me:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:
The following packages have unmet dependencies:
boinc-amd-opencl : Depends: amd-libopencl1 but it is not installable
E: Unable to correct problems, you have held broken packages.
VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV770 [Radeon HD 4870
How do I install an opencl supported driver for this card?
