Are you packaging the kernel as an RPM? If so, what kernel version are
you basing on?

As mentioned before, Fu Wei has done some work on the A10 kernel as
well, so maybe you could coordinate efforts.

Also, if you have the kernel package in a yum repository, we should be
able to generate images relatively easily using livemedia-creator and a
kickstart. The only 'trick' would be getting the U-Boot configuration
set up correctly. I could help set up the kickstart file, if you
provide the U-Boot configuration information, and would like to pursue that.
