[gentoo-user] Makeing /dev/rtc1 accessible as soon as possible - how?

Hi,

There are two RTCs in my system:
/dev/rtc0 and /dev/rtc1

rtc0 is not powered by a battery and forgets time/date
with system shutdown and rtc1 is a I2C-rtc (DS3231) which
is powered by a battery. It is extremly accurate in comparison
with rtc0.

rtc0 is accessible with system boot - rtc1 is not (current state).

To make rtc1 completly know to the system, I have to do a 
    echo ds3231 0x68 >! /sys/bus/i2c/devices/i2c-1/new_device
    hwclock -f /dev/rtc1 -s
in beforehand.

I wrote a script for /etc/init.d, which does exactly this, and 
the system login screen shows the correct tome/date information
even without ntp-client (the system should become independantly
from lan/internet). The script was added to the boot service 
and executed after dev and modules.

The kernel is configured to use /dev/rtc1 and the driver for the
ds1307, which also handles the ds3231, is included into the kernel
(no module).

But it seems, that setting the system time this way is too late,
since there are still (for example) log files under /var/log
with a timestamp of the 1.1.1970.

Are there any other way to make rtc1 known and accessible earlier 
to the system as the hack via a script in /etc/init.d ?

Thank you very much in advance for any help!
Best regards,
mcc
