NGen Issue - System.dll

I am POCing NGen for our application to help improve startup times on
slightly older hardware.
I have run into a bit of a snag with regards to System.dll. As it is a
dependency of many of our assemblies, the native version of System.dll is
necessary. It appears that System.ni.dll exists in the NGen cache, but for
some reason when the load is attempted it fails to "resolve" to the native
image, subsequently causing our application native image loading to fail.
A little background... Our application consists of multiple .Net processes.
I am attempting to NGen them one at a time to see if there is any
perceivable performance gain. One thing that I have not done *yet* is
adjusted the assembly base addresses. We have hundreds of assemblies, what
is the best way to approach this? I understand that until this is completed,
the full potential of NGen may not be realized. Correct?
Also, the assemblies of our application that I am NGening are *not* in the
GAC. Some are, but the majority of them *are not*, and they live in their
installed "Program Files/blah/bin" directory.
Here is a sample fusion log of the System.dll issue I am seeing. I have
adjusted the assembly names (Assembly1,2,3) and paths for security reasons.

Native image has correct version information.

Rejecting native image because dependency
C:\WINDOWS\assembly\GAC_MSIL\System\2.0.0.0__b77a5c561934e089\System.dll is

Discarding native image.
Thank you for the help!
