No, it's also used by ps to resolve WCHAN in "ps -xl".
The situation is awkward if you have the wrong version of System.map in /boot and you run "ps -xl". It will resolve the WCHAN numbers to names, but the names will be wrong. Very confusing. I agitated to include a step about copying System.map to the right place in the kernel install documentation / scripts, but I don't think it happened.
