Yes and no. There are a few fields in the FACP (Fixed ACPI description
table) and in other bitfields which allow the OS to know whether it was
awaken by the RTC, and if that capability is supported in the first place.
I've found nothing saying how to set the RTC alarm time ; but the ACPI
spec is extremely messy^H^H^H^H^Hfeature-rich and there might be some
configuration method lurking around in the name space tree, but my AML
interpreter is still too sketchy to let me see right now.
