Yes, I see that /lib/modules is empty.    I wonder if there is a way to get the build-arm-rootfs script to include  the modules we need...

Yes - the instructions do work but I followed a "slightly" different path
(grin).  Guess I should have mentioned that part (duh - late, too much
coffee, etc).

I did not download the kernel (uImage), boot-loader (u-boot.bin), nor the
MLO files as specified - I used my existing 2.6.29-rc2 kernel image and the
other files I had created in a previous build of omap3-console-image and
omap3-desktop-image as they had some extra drivers activated (as modules)
for some of the hardware I am using which was not active in the factory
configured kernel.

Being as it may - when I checked in the /lib/modules directory in the Overo
ubuntu filesystem there were not any modules loaded at all - the directory
was empty.

I copied the module files from my working microSD card to the card
containing the ubuntu filesystem and it worked correctly - during the bootup
process the system detected and loaded the correct kernel hardware modules
(USB 10/100 ethernet dongle, wireless keyboard and mouse and my Wifi
dongle).  I had to configure the network settings in /etc/network/interfaces
to bring up the ethernet and wifi interfaces but I had expected that.  Once
the network was up and active I performed the 'apt-get update' command which
performed properly and tested it by installing nano (which is not part of
the initial filesystem load).  So far things are working properly (as far as
I can tell at the moment).

In looking at the directions there is no mention of installing the kernel
module files - this is not a problem if all the kernel modules are compiled
directly into the kernel but in my case that was not the case (too many
cases???).  To be fair about it the directions DO work in getting Ubuntu
installed and loading on the Overo - it is just missing a couple of "minor"
details to make it useful (grin).

Now - if I can just get a LAMP system configured (grin).

The really slick part is my power meter reports the Overo Ubuntu system is
drawing a whooping 4 Watts of power.  Can you say "DEEP DEEP GREEN" (grin).
