Dear Michel, Sorry for taking so long for getting back to you, but I have some moderately detailed results.

Oh, one correction: the R400 above was a typo. It should have been R300. >>> What's the problem(s) you're having? >> >> Everything is falling back to software rendering and using the CPU to the >> maximum. >> >> Do you want me to show you the output of glxinfo with debug information? > > That, and the corresponding Xorg.0.log and dmesg output (at least the > agp/drm/radeon related messages) should be a start. OK. I just put a before-and-after comparison on my homepage at: http://www.ime.usp.br/~rbrito/linux/debug-r300/ There you have a description of the notebook, and logs from it running both the 2.6.32 and the 2.6.38 debian kernels. Please, notice that I have reverted X to the state at stable, but everything that I said there holds true to the software rendering problem with KMS. When I use UMS, I get *much* faster framerates in an OpenGL benchmark available in the repositories (package: globs). If you need anything else, please let me know.
