I see ... because platform_device_register() will device_initialize()
which clobbers that state, before doing platform_device_add().  I
wonder what bugs are lurking thereby.  :(

This last version looks clean and OK, so long as the driver registers
after that arch_initcall().

Really, no day field in the alarm for that particular southbridge?
Too bad.  And a bit surprising ... I thought current versions of
ACPI required the up-to-one-month enhancement to mc146818.
