It depends from what you want to do, but i think that the correct approach 
in this case is ptracing the process.

in this project 
http://savannah.nongnu.org/projects/view-os
we use ptrace for modifying system calls behavior.

we get, modify, and restore register using the ptrace() syscall 
( There's also a patch for making all this more efficient )

Bye!
