Perhaps we should have "make install" of a kernel also install this
library?

Have two libraries? One that is linked to the app, the other that can
search for another library to link on load too (like a kernel.ld.so)

Then we could see the kernel version, and search for a library that is
compatible, and load that one.

The app only needs to worry about loading the generic library. The
generic library can test for compatible libraries for the kernel.

Could just be..

  libkernel.ld.so  which then loads..

  /lib/modules/2.6.36/libkernel.so


Just a little brain storming.
