It appears that drivers/acpi/sleep/proc.c contains the following code:

#if defined(CONFIG_RTC_DRV_CMOS) || defined(CONFIG_RTC_DRV_CMOS_MODULE) || !defined(CONFIG_X86)
/* use /sys/class/rtc/rtcX/wakealarm instead; it's not ACPI-specific */
#else
#define HAVE_ACPI_LEGACY_ALARM
#endif

I believe the i386 kernel does not have CONFIG_RTC_DRV_CMOS defined, but the x86_64 version has, hence only the i386 version enables /proc/acpi/alarm.
