How can I locate this previous report?  (identified below)
I am willing to spend some time pushing Xenomai forward on this front, but I will probably need some help. I have been involved with Linux system building just long enough to be dangerous. Installing a co-kernel is a new frontier for me.

Normally, when I need to attach a new module to the Angstrom kernel, I...
  1. bitbake the Linux system. (Kernel source is deleted upon completion.)
  2. bitbake the Angstrom kernel using the "-c compile" option, which leaves the kernel source and intermediate files in place.
  3. Build my kernel modules within the context of the kernel.
My theory is that the below sequence may work for Xenomai...
  1. bitbake the Linux system. (Kernel source is deleted upon completion.)
  2. bitbake the Angstrom kernel using the bitbake "-c compile" option, which leaves the kernel source and intermediate files in place.
  3. Apply the appropriate Adios kernel patches.
  4. Rebuild the Angstrom kernel using the "-c compile" option, which should use the patched  kernel source.
  5. Add the Xenomai sub-tree to the root file system.
  6. Build my modules as before.
Does this make sense?

What I really want to do is install Xenomai into the BeagleBoard 
Angstrom kernel.
    

Yes, recently someone reported using this method. However, he had issues
with -Wl,--as-needed which we did not elucidate completely.
