Ah, interesting. I have two observations about that patch:

- you were moving basically in the opposite direction that I am
  trying to bring it now. ;-)

- I see now that four defconfigs (gamecube, powernv, pseries and wii)
  do enable RTC_DRV_GENERIC. For some reason, ppc64_defconfig only
  enables RTC_DRV_DS1307, I assume that is not intentional.
