Am I using the "ati" or "vesa" driver?

Are you speaking about the segmentation fault + backtrace problem?
I have built "mesa-10.0.2" with the "--with-egl-platforms=drm" option but I have again this segmentation fault + backtrace problem.
It does not solved this problem.

Here is the exact configuration line I have used:
./configure --prefix=/usr --sysconfdir=/etc --libdir=/usr/lib --mandir=/usr/man --docdir=/usr/doc/mesa-10.0.2 --with-dri-driverdir=/usr/lib/xorg/modules/dri --with-dri-drivers="i915,i965" --enable-shared-glapi --with-egl-platforms=drm

I am building and installing packages in this order:
- libdrm-2.4.56
- mesa-10.0.2
- mesa-demos-8.1.0
- fontsproto-2.1.3
- glproto-1.4.17
- libepoxy-1.2
- xextproto-7.3.0
- xproto-7.0.26
- xtrans-1.3.4
- xorg-server-1.16.0
- glamor-egl-0.6.0
- xf86-video-ati-7.4.0
- xf86-video-intel-2.99.912
- xf86-video-vesa-2.3.3

Anyway, if I keep the official packages from Slackware 14.1, I have not this segmentation fault + backtrace problem.
So, currently I am using:
- libdrm-2.4.46
- mesa-9.1.7
- mesa-demos-8.1.0
- fontsproto-2.1.2
- glproto-1.4.16
- libepoxy-1.2
- xextproto-7.2.1
- xproto-7.0.24
- xtrans-1.2.7
- xorg-server-1.14.3
- glamor-egl-0.6.0
- xf86-video-ati-7.2.0
- xf86-video-intel-2.21.15
- xf86-video-vesa-2.3.3

In this second case, the problem is that I have no direct rendering.
As you can see here:
$ cat /var/log/Xorg.0.log | grep Direct
[  7567.271] (WW) RADEON(0): Direct rendering disabled

The full xorg log is available here: http://pastebin.com/hSKjXsvL

Maybe, it is just a permission problem, a xorg configuration problem, or something like that.

What can I do to get direct rendering please?
