kernel source, drivers/char/rtc.c

                /*
                 * We don't really want Joe User enabling more
                 * than 64Hz of interrupts on a multi-user machine.
                 */
                if ((rtc_freq > 64) && (!capable(CAP_SYS_RESOURCE)))
                        return -EACCES;


So, you can either

edit that (mplayer wants 1024) and recompile the kernel driver, set mplayer
suid root, or simply run it as root.
