You need to enable DRI, look in the maling list, it was asked some weeks ago. 
With glxinfo you should see a line "direct rendering: Yes" if enabled. 

Basically, if you are using default stock kernel, you only need to
load your chipset AGP support for DRM (agpgart and one of the
intel-agp via-agp, this dipend on your motherboard),   then you need
to load the "radeon" module and then start X.

With the latest hotplug, probably the version present in Sarge should
be enough, the loading stuff should be automatic, if not you can use
your /etc/modules file.


P.S. you can squeeze some FPS adding a couple of line to your
XF86config-4, like enabling page flip and fast write:

Section "Device"
        Identifier      "Generic Video Card"
        Driver          "ati"
        Option          "AGPMode"  "4"
        Option          "AGPFastWrite"  "on"
        Option          "EnablePageFlip"  "on"
