Asymmetric display configuration?

We've got a 3x3 display wall with several of the displays driven by 
dual-head NVIDIA Quadro FX 2000 cards.  9 displays, 5 PCs, 5 cards.  We can 
get DMX to run on a configuration where all but one of the displays is on a 
dual-head card.  DMX has no problem working with the X displays :0.0 and 
:0.1 on each of the dual head machines.  So far, we have not succeeded in 
getting chromium to do the same thing.

So we modified some of the dual heads to use twinview, so the display is 
only :0.0, and chromium will run on top of DMX in this configuration.  But 
the twinview only seems to work if all the twin views are in the same 
configuration - below, rightof, etc.  In this case we've set up the bottom 
6 in a 3x1 twinview format (using the 'Below' setting).   But that leaves 
the remaining 3 displays.  We would like to  use the remaining two machines 
to cover these last three displays, but that means that one would be a 
single display, and the remaining two would be in twinview but with a 
'RightOf' setting.

DMX has no problem with this configuration.  But, so far, we haven't found 
a way to get chromium to run on this configuration.  We are using 
modifications of the dmx.conf file.

So - the question is - does chromium support asymmetric display 
configurations like the one we'd like to create?  Is it just a matter of 
getting the right hand-crafted configuration file set up?  Or is this just 
too much of a burden for chromium's mind?
