See https://bugs.freedesktop.org/show_bug.cgi?id=3130

You can use 'driconf' to enable 1024x1024 textures.  But since a few 
months (since Mesa-6.5.3) 'glxinfo' segfaults (for me at least), so 
'driconf' doesn't work any more.  You can maybe get away with 
putting this into your .drirc:

<driconf>
    <device screen="0" driver="unichrome">
        <application name="Default">
            <option name="no_rast" value="false" />
            <option name="vblank_mode" value="0" />
            <option name="excess_mipmap" value="true" />
        </application>
    </device>
</driconf>

You might want to join #unichrome on irc.freenode.net.
