But it does boot with out errors?
Can you install (just CentOS) using it but without using the kickstart file?

Are you starting with the kernel SRPM from CentOS?
When I did something similar for a system needing to boot from USB on RHEL 4, I started with the
srpm for the kernel that matched the kernel that would be installed by the "cold install", and used
the config files that came in it.
I had to mod the config file to force all the USB physical devices I new were going to be used in
the install process to be built in, IIRC I figured out that I did not want to mess with all the
modules and I did not want to mess with the contents of the initrd provided by RH (it broke bad
anytime I did), so I ONLY forced with the USB to not be a module and let the other modules be
provided by the contents of the original initrd.
secondary trick, change all the "%define build*"s in the spec file that you don't need to 0.
it speeds up the build a lot.
