Works here!

There are actually 4 options, some will not work yet, though:
  1. CONFIG_RTC_CLASS=n, CONFIG_GEN_RTC=[my], /dev/rtc = 10,135
     This is what I was using, using the deprecated generic RTC interface.
  2. CONFIG_RTC_CLASS=n, CONFIG_RTC=[my], /dev/rtc = 10,135
     Old style CMOS RTC driver, used to work on PC and Atari.
  3. CONFIG_RTC_CLASS=y, CONFIG_RTC_DRV_GENERIC=[my], /dev/rtc is dynamic
     Should work, as of 2.6.30-rc1, using RTC class on top of the
generic RTC interface.
  4. CONFIG_RTC_CLASS=y, CONFIG_RTC_DRV_CMOS=[my], /dev/rtc is dynamic
     While rtc-cmos can be enabled on Atari (it was derived from
rtc.c), it won't work yet,
     as the necessary rtc_cmos platform device is not yet created on Atari.
