That code is only executed if the '-h' option is passed to halt: Some distros (namely Slackware 7.x) pass the '-p' option instead (look in /etc/rc.d/rc.0).
Ok how about this: I'm current testing some patches against ide.c and friends. Why don't I just add ( and document ) a define called NO_STANDBY_ON_SHUTDOWN which would live in ide.c. By default it would not be defined. Then I just wrap the standby code in an '#ifndef NO_STANDBY_ON_SHUTDOWN..#endif' block.
