No longer necessary: The newer kernels [1] have a driver for /dev/rtc that lets you use the standard hwclock utility from util-linux. Just choose CONFIG_PPC_RTC=y when compiling your kernel (or choose CONFIG_PPC_RTC=m and patch a small bug in arch/ppc/kernel/ppc_ksyms.c) [1] 2.2.17preX since X=5; recent 2.4.0-test from bitkeeper and Paul's trees. -- Martin
