Try lsmod
and see if the driver for your RTC is listed. If not, try dmesg (I usually use dmesg | less, f is forward, b is backward, and q is quit) and search for a message which may indicate a problem loading the driver. Look for the character device /dev/rtc1 Also, hwclock command behaves strangely sometimes, try sudo hwclock from a regular user account instead of from root. There may be some funky permission issues.
