So it might be merged into 2.6.38, it doesn't seem like a huge change to allow compressed textures through it.
S3TC is working nicely for me. Darkplaces engine with Tecnox mod running 55FPS at 1366x768. Oh yeah... the hardware is a Acer netbook (AO721) with single core K125 & M880G (R600) GPU. I'll have to try a more recent game engine soon as time allows.
Kernel 2.6.28-rc5 & Mesa from git.
That's strange that WoW doesn't render correctly for you. It works for me on my 4850.
Player models aren't all messed up or anything. I used to have that problem, but it went away after going to the latest Mesa and doing all the stuff to enable S3TC including using the kernel from drm-radeon-testing.
The only problems I had with WoW was the performance wasn't that good (10-20fps), and the icons for items and abilities would sometimes not render correctly. And going underwater gives you a psychedelic view.
I'm using the edgers ppa 2.6.38-4 kernel.
I don't have enough space to compile the kernel myself unless I can do it from an ntfs drive.
S3TC does not work for me. I am using r600g from mesa-9999 (compiled with R600_ENABLE_S3TC=1, USE_EXTERNAL_DXTN_LIB=1), xf86-video-ati-9999, libtxc_dxtn-1.0.0, drm-radeon-testing (2.6.38-rc8-44191-g38f1cff), libdrm-9999 and even wine-9999, all checked out in the last hour and...
but...Code:glxinfo |grep -i s3tc GL_NV_texgen_reflection, GL_NV_texture_env_combine4, GL_S3_s3tc, GL_EXT_texture_compression_s3tc, GL_EXT_texture_env_dot3,

- NWN and native Unreal Tournament look like some distorted, multiplied slices: http://img192.imageshack.us/i/nwn.png/
some weeks ago it worked, but I don't know how and why this changed, but the result obviously sucks
