ATI 9000 direct rendering question

[Pablo Wolter]

Hi,

I have a couple of questions and googling cannot find something that I
understand 100%.

I have Hoary, I know that this comes with X.org instead of XFree86 but
under /etc/X11 I have both configuration files.

I have the ATI Radeon Mobility 9000 M9 (R250 Lf), but glxinfo shows:

...
direct rendering: No
server glx vendor string: SGI
server glx version string: 1.2
...
client glx vendor string: ATI
client glx version string: 1.3
...
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.2 (1.5 Mesa 6.2.1)
...

My questions are: Wich of the two files or X window system I'm using
X.org or XFree86? How I can enable direct rendering? and finally: Why I
have those two files if I install just Hoary and not upgrade it from
previous version?

Any link or tip will be great and sorry if this questions are a kind of
basic ones, but I cannot figure out this things.

Pablo.
