Using openembedded with externally built kernel

[Carlos Rafael Giani <dv@pseudoterminal.org>]

I have a platform with a very barebones BSP that builds and patches a 
2.6 kernel using a whole lot of shell scripts and patch files.
Integrating this build process into a .bb file is too complicated at the 
moment.

Since cross compiling all packages I need is a nightmare to do manually, 
I wonder if I can get OE to use the prebuilt kernel along with
its kernel modules and headers instead of trying to build a new kernel. 
Ideally, I would just tell it where the kernel headers are, where
the uImage is, and where the modules are. I imagine this as some kind of 
kernel .bb file setting things up to not actually build anything.

My question is: is this possible? All I could find was about external 
toolchains and external kernel modules.
