The reason why the Radeon HD 5970 supports Eyefinity now is because it was easier to get working first. The onboard PLX PCIe chip on the video card gives AMD a known set of PCI Express lanes to work with, and knowing that the configuration will never change they were able to get Eyefinity working with this configuration first. A future driver down the road (not Catalyst 9.12, so think 2010 for support) will enable CrossFire on Eyefinity for all other configurations.
Wow, this completely sucks. My second 5870 is basically a $400 paper weight for at least the next two months.
In hind sight, I suppose I should have waited before buying two 5870's and three Dell monitors for Eyefinity.
