openCL and AMD SDK 2.4

I have 2 radeon 6970 cards in a 11.4 system. X works well, the fglrx driver is loaded, and aticonfig displays my cards.

However if I install the AMD SDK 2.4 and try the default clinfo it only lists my CPU. It doesn’t see the GPU.

I thought this might be a driver issue so I have tried a few catalyst drivers, from the latest to a few months old. They all give me the same issue.

I haven’t had the problem with ubunutu, so it must be something I’m missing. A few wiki pages say that after changing drivers to run sax2, but that isn’t applicable on this version.

Any suggestions would be helpful.
