Why do you need to keep an index of all the locations in the OSDA? It should be enough to use normal variables within the kernel, and have the linker hard-code the addresses.

What are kernel variables, if not 'locations in the system area' which are 'built at runtime'? What advantage is there in having an 'OSDA'?

I'm not saying it's a bad idea... I just didn't/don't see you reasons for having it that way.
