I don't understand. Why do you need to modify these functions? They already work! All I have done is to create a character driver that calls them (via their pointers ppc_md.set_rtc_time, and ppc_md.get_rtc_time). The driver registers itself on the standard rtc major and minor numbers and supports the standard RTC_RD_TIME/RTC_SET_TIME ioctls. What is genrtc? (I'm not using 2.5 yet.)
