Please try these 3 things independently:
1) Create an /etc/X11/xorg.conf with this contents:
Section "Device"
  Identifier "myradeon"
  Option "SwapbuffersWait" "False"
EndSection

2) Create a .drirc file with this contents:
<driconf>
    <device screen="0" driver="dri2">
        <application name="Default">
            <option name="vblank_mode" value="0" />
        </application>
    </device>
</driconf>

3) This would work in Ubuntu 10.10 but I think not in 11.04 (gallium needs KMS):
Boot with adding this to the kernel options in the grub menu: radeon.modeset=0
