Apparently something is amiss in the initramfs preventing access to the
rtc, and once the real root filesystem is mounted, rtc access works. I'm
not sure where to look or how an error might have crept in, but when I
unpack my initramfs on a couple of systems (it's a compressed cpio
archive) and grep for "rtc", I find:
./etc/modprobe.d/dist.conf:alias char-major-10-135 rtc
./etc/udev/rules.d/50-udev-default.rules:SUBSYSTEM=="rtc",
DRIVERS=="rtc_cmos", SYMLINK+="rtc"
