I use a DS1672 RTC and as long as support for it is enabled in the kernel 
it will:
 - set system date/time on boot
 - android's ntp client will update the rtc (you can verify this with 
hwclock)

I'm not sure I understand the question - is the above not occurring for 
you? What do you see with 'ls /dev/rtc*'?
