[Libdlo] Getting things up on CentOS

[Dave Henning]

I am using the IOGear DisplayLink USB to VGA Adapter.  I got it more or
less working on Ubuntu 9.04, but my customer requires getting it working
on CentOS 5.3 or at least starting with CentOS 5.3 and upgrading only
the necessary drivers needed to get the DisplayLink working.
 
I was able to see graphics on Ubuntu 9.04 using the instructions from
the Mulchman blog (which was referenced on this mailing list.)  

I moved over to CentOS 5.4 and tried to translate the recipe for Ubuntu
9.04 found on the Mulchman blog.  

http://mulchman.org/blog/?tag=displaylink

Once I did this, plugging in the DisplayLink adapter caused the machine
to completely freeze requiring a power cycle.  I then tried it on a
CentOS 5.3 installation and that did not work either.

I tried to log each step below.  I am very new to RedHat/CentOS so I am
hoping there is something obvious missing here.

Thanks,
Dave ...
