[ntp:questions] reference clock driver for /dev/rtc

Hello,

I need to synchronize my Linux system via ntpd and use /dev/rtc (CMOS clock) as a time source. I have very accurate RTC.
I have seen a hint on http://www.denx.de/wiki/view/DULG/UseNTPToSynchronizeSystemTimeAgainstRTC that the reference clock #43 is RTC. But my distribution (Suse) does not support RTC.

Is there any implementation which supports RTC?

Thank you!

Pavel
