basically you have to set the wakeup time in /proc/acpi/alarm
echo "YYYY-MM-DD HH:MM" > /proc/acpi/alarm
then give a shutdown and check if your system works well with with
acpi wakeup. (perhaps you have also to check the settings in your
if everyting works, well ! you can begin tuning up mythwelcome, using
the acpi commands instead of nvram ones.
there is a page in the wiki for the acpi wakeup (check for this words
and not for RTC) and searching for gossamer threads you can find also
information about acpiwakeup and mythwelcome.
the only problem I found is for the BIOS configured to use UTC instead
of localtime; in such case, you have to tell your linux box your BIOS
is using UTC.
