But I don't think the CONFIG_RTC_CLASS=y is correct for the Amiga kernel builds
but it is selected in the .config for the -amiga kernels available from
(the 2.6.26 and 2.6.28 that I have looked at, anyway).
I believe that CONFIG_GEN_RTC=y and CONFIG_GEN_RTC_X=y should be the proper
selections and CONFIG_RTC_CLASS should not be set. These are the defaults for the m68k arch.
I am currently building a kernel with these selection changes to verify (22.214.171.124).
