If I create rtc under /dev manually with mknod(it's lost when I reboot of course), Mplayer still fails to find it.   I've added 'echo "dev.rtc.max-user-freq=1024" >> /etc/sysctl.conf' as suggested in BLFS, but this is giving the error: 'error: "dev.rtc.max-user-freq" is an unknown key', but then it would, wouldn't it?      

If mplayer works then the `problem' doesn't sound too bad. Please post 
your kernel .config
