Thanks for yor reply but ... you are streets ahead of me.

I have RTC alarm enabled in BIOS and the alarm starts my machine from 
Soft-off and boots correctly at, in my case, 23:05 every evening, and 
not at 00:00 or any other time. At 23:10 cron starts my daily jobs.

I think I am not interested in any further RTC alarms, which will not
happen for 24 hours anyway.

My problem is to decide at the end of the daily jobs whether to switch
off the machine with /sbin/halt (if RTC started my machine) or not to
switch off (if pressing the power button had started the machine).

Are you saying that testing (after installing the patch) either RTC_STS 
or RTC_ENA would give me my answer.

Before installing the patch I see no both bits look identical when 
switched on by hand or by RTC. Sorry, I am an acpi-newbie and probably 
missing something.
