I have wine 1.3.8 as well, didn't use winetricks for d3dx9, instead just copied the d3dx9_36.dll to the lotro directory, which worked perfectly with the proprietary ATI driver.

Didn't get anything from xorg-edgers. Someone on the IRC channel told me texture compression is simply not yet supported by libtxc_dxtn for r600 cards and above. Seeing as I have an ATI HD 4870, which is a r700 (I think), this situation is hopeless for me I guess. I'll just have to stick with the proprietary one and try to get my performance up.
This makes sense. Although, I'm not sure if libtxc_dxtn is not an abandoned project.
Also, I think this is a good description of the situation with S3TC and MESA
