Hmm.. when I'm comparing the config files for the current stable kernel and this one I see the following of note:

2.26.35.7 | 2.26.36
----------------------------------------
CONFIG_RTC_CLASS=m | CONFIG_RTC_CLASS=y
CONFIG_RTC_LIB=m | CONFIG_RTC_LIB=y

Perhaps this has to do with this https://bugs.archlinux.org/task/21137 and there is only some change in rc.sysinit missing.

This harmless message is due to an incomplete implementation of  FS#21137 : CONFIG_RTC_DRV_CMOS is still set to 'm', but  FS#21137  requested that it be set to 'y', along with RTC_CLASS and RTC_LIB. Without building in RTC_DRV_CMOS, this is actually not very useful, as the kernel fails to read the hardware clock (this is what the message indicates).

There is no negative impact on system operation for now, but we should fix this before moving to core to implement  FS#21137 .
