direct rendering is always "Yes" these days, because mesa includes a
software render which makes you CPU do all the work.

try: glxinfo | grep "^OpenGL"

here's what I get on my Intel Laptop:
OpenGL vendor string: Tungsten Graphics, Inc
OpenGL renderer string: Mesa DRI Intel(R) 945GM GEM 20100328 2010Q1
x86/MMX/SSE2 OpenGL version string: 1.4 Mesa 7.8.2

and here's what you SHOULDN'T get (from a VM with cirrus-vga):
jinks at edultsp:~$ glxinfo | grep direct
direct rendering: Yes

jinks at edultsp:~$ glxinfo | grep OpenGL
OpenGL vendor string: Mesa Project
OpenGL renderer string: Software Rasterizer
OpenGL version string: 2.1 Mesa 7.7.1
OpenGL shading language version string: 1.20

(Note, that it still supports direct rendering, but uses the Software
Rasterizer.)
