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

Yes, for xorg-server-1.16.0, no problem I can use the embedded glamor.
When I am compiling xorg-server-1.16.0, I do:
$ ./configure --prefix=/usr --libdir=/usr/lib --sysconfdir=/etc --localstatedir=/var --infodir=/usr/info --mandir=/usr/man --disable-static --with-pic --with-int10=x86emu --with-default-font-path="${DEF_FONTPATH}" --with-module-dir=/usr/lib/xorg/modules --with-xkb-path=/etc/X11/xkb --with-xkb-output=/var/lib/xkb --enable-config-udev --disable-config-hal --enable-glamor
I think that the "--enable-glamor" option means I will use the xorg-server-1.16.0 embedded (internal) glamor version, isn't it?

Now, the problem is that without the external glamor, I got an error from the radeon driver:
[ 44144.759] (EE) RADEON(0): glamor not available
And I again no have 3d acceleration:
[ 44144.801] (WW) RADEON(0): Direct rendering disabled

Why I have no 3D acceleration please?
