We are currently discussing the mess with separate patch strategies
for the kernel headers and the linux build.
I proposed that both the kernel-headers and the linux should use the same patch directories.
This is only the case, if the kernel-headers and the linux version are the same today.

A long term approach could be to keep the kernel-headers for pre 2.6.19 kernels only
and build the headers in the target/linux directory, with patches
divided into groups of patches which are or are not applied depending on 
menu configurations.

Typically you would have 
"core" patches              - always applied
"architecture" patches   - always applied if an architecture is selected
"board" patches            -  conditionally applied through a choice.
