So, this is almost the same as me, except i have a ds1385-rtc compatible version, and some interrupt stuff. Can you confirm that the GEN_RTC driver works for you ?

To my surprise, genrtc in 2.4.23 does not work on my LongTrail! The kernel crashes in init/do_mounts.c:mount_block_root() right after the call to sys_chdir(), because current->fs is a NULL pointer. Weird, and it doesn't really look genrtc-related, although the same source tree works fine if I disable genrtc and build in rtc. I also tried 2.6.0, and there it works fine, both in the builtin and modular case: the kernel got the correct time, and hwclock works.
