Hi,

I have 2 problem with my mesa
1) I can't replace swrast with r600 dri.
2) I can't even run gallium swrastg.

My system:
Gentoo amd64, IGP RS780
xorg-server-1.8.0, libdrm-2.4.20,
xf86-video-ati-9999(git://anongit.freedesktop.org/git/xorg/driver/xf86-video-ati:master),
mesa-9999(git://anongit.freedesktop.org/mesa/mesa:master)
results are same with xf86-video-ati-6.13.0 and mesa-7.8.1

1)

It looks like everything is OK, but my glxinfo still report this:
----------------------------------------------------------------------------
OpenGL vendor string: Mesa Project
OpenGL renderer string: Software Rasterizer
OpenGL version string: 2.1 Mesa 7.9-devel
OpenGL shading language version string: 1.20
----------------------------------------------------------------------------

Guy reporting "https://bugs.freedesktop.org/attachment.cgi?id=34651" has slighly different GPU (RV670), his dmesg and Xorg.0.log are almost same as my logs, but his glxinfo is different:
----------------------------------------------------------------------------
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: Mesa DRI R600 (RV670 9505) 20090101  TCL DRI2
OpenGL version string: 2.0 Mesa 7.9-devel
