AFAICT, debuggers can set breakpoints on arbitrary code lines without grepping
through assembly language. If you don't have the debug information available,
then using a debugger is pointless anyway.
This is beyond silly. If we follow your argumentation we need another
gazillion of conditional breakpoints in the kernel. Definitely not.
