Now that I recall, you are correct-- I could get the OpenCL software to install, but I couldn't get it to see the GPU hardware, just the CPU. Sorry, this all happened a few weeks ago and I gave up... but now I'm wanting to try it again.
Sounds more like you didn't have the OpenCL drivers installed for your card. AMD has/had at one point two different versions of their driver packs, one that included OpenCL support and one that didn't.
