You are truly a god among developers - this works perfectly, straight out of the blocks. Here's the config I'm using:

</resourceGroup><resourceGroup>
        <name>3x2-rearranged</name>
        <handler>tiled_display</handler>
        <description>Rearranged connections</description>
        <handler_params>
                block_type='gpu';
                num_blocks=[2,2];
                block_display_layout=[2, 1];
                group_blocks=[2, 2];
                combine_displays=True;
                display_device='Dell 3008WFP';
                display_mode='2560x1600_60';
                remap_display_outputs=[2,3];
                framelock=False;
                clip_last_block=[1,None];
        </handler_params>
        <resources>
                <reslist>
                        <res><server><hostname>localhost</hostname></server></res>
                        <res><gpu><hostname>localhost</hostname><index>0</index></gpu></res>
                        <res><gpu><hostname>localhost</hostname><index>1</index></gpu></res>
                        <res><gpu><hostname>localhost</hostname><index>2</index></gpu></res>
                        <res><gpu><hostname>localhost</hostname><index>3</index></gpu></res>
                        <res><keyboard><index>0</index><hostname>localhost</hostname></keyboard></res>
                        <res><mouse><index>0</index><hostname>localhost</hostname></mouse></res>
                </reslist>

        </resources>
</resourceGroup></resourcegroupconfig>

Aside from being caught out at first by using 'none' instead of 'None', and having to rearrange the cabling (thankfully displayport is much nicer than DVI in that regard), it was as simple as creating the tiled display and adding the clip_last_block line. Running from the console works perfectly.

Thanks for implementing this so quickly!
