Chromium breaks after upgrade to Ubuntu 10.04

I have a tiled display of with 16 nodes, and a master server.  This
"display wall" previously ran Ubuntu 9.04, but I decided to move
everything to 10.04.

When I made the move to 10.04 Chromium applications no long launched.

If I do something like:

display@master4:~/master4/demos/chromium/cr-1.9/mothership/configs$
python sweetmural.conf

I get the following output:

Real width: 13440, Real height: 4200
This is Chromium, Version 1.9
Autostart for node precision13: ['/usr/bin/ssh', 'precision13',
"/bin/sh -c 'LD_LIBRARY_PATH=/home/display/master4/demos/chromium/cr-1.9/lib/Linux
/home/display/master4/demos/chromium/cr-1.9/bin/Linux/crserver
-mothership master4'"]
....
....
CR Warning(precision1:1640): Render SPU: Display :0 doesn't have the
necessary visual: RGB, Doublebuffer, Z
CR Warning(precision1:1640): Render SPU: Couldn't get a visual,
renderspu_SystemInitVisual failed
CR Warning(precision1:1640): Render SPU: Couldn't create a window,
renderspuFindVisual returned NULL
CR Error(precision1:1640): Render SPU: Couldn't get a double-buffered,
RGB visual with Z!

All of the nodes have the nvidia drivers. I even double checked that I
was getting hardware acceleration on the nodes with the following
commands:
display@precision1:~$ export DISPLAY=:0
display@precision1:~$ glxinfo
name of display: :0.0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4
...
...


Has anyone else experienced a problem like this?
