The problem isn't the GPUs, it's the fact that the GPU cores are not designed properly to take advantage of them. And I doubt that will change any time soon, since ATI's degree of involvement with the project has not changed.

Don't get your hopes up.

Hopefully their next-gen chips will take GPGPU apps into a bit more consideration.
Actually, one of the problems with the current cores is that they don't make use of the local data stores in RV770 and RV870 AT ALL, which leads to a lot of repeat calculations being performed. Right now it doesn't matter how much cache the SPs have if it isn't being used altogether. And I'm not convinced that the size of the LDS will even be a bottleneck should it start to be used. The only way to make that assessment would be to actually test it out and see what the performance results are.
