I haven't looked into the acpi_walk_namespace() question.

But I did look at the acpi_rtc_init() stuff, and I have to say it
looks like a really round-about way to accomplish this. I'd rather
just fold in the FADT accesses directly into cmos_do_probe() and
dispense with the stuff in drivers/acpi/glue.c. I'm working on a
couple patches along this line, but it will take me a few days to
finish up.
