Well, I often use the hex numbers to look them up and disassemble them 
in a vmlinux via gdb and 'list *0x1234123412341234' - where the 
vmlinux has no debuginfo. (Debuginfo takes longer to build so I 
generally build without it.)

I'm quite sure other kernel developers do that as well.

AFAICS this won't work in a symbol-less vmlinux. Is there some trick 
to do it with gdb?

Thanks,
