It is a nice approach, but I wonder whether the kernel's gdb stub could use the existing qXfer:libraries remote protocol packet. And, if not, could we extend gdb to make it work.

The simplest is introducing a function that is called at the right spot with the right arguments. It doesn't need to do anything, just be a name where you can put a breakpoint. Jan> + import symbols I think it's better to put everything into its own package, e.g. 'import linux.symbols', to try to avoid conflicts with other python modules that may get loaded.
