I've got this working on my netbook now, based on the info from the
mythTV folks:
http://www.mythtv.org/wiki/ACPI_Wakeup
I'm currently doing it externally in a cron job, using the following
script:
----------------cut here--------------------
#!/bin/sh
delta=960
nextevent=`konsolekalendar --next  --export-type=csv |
        sed -e 's/"\([^,]*\)","\([^,]*\)",.*/\1 \2/'|
        grep 'm$' |
        head -1`

nextevent=`date --date="$nextevent" "+%s"`
nextevent=`expr $nextevent - $delta`
echo 0                         > /sys/class/rtc/rtc0/wakealarm
echo $nextevent                > /sys/class/rtc/rtc0/wakealarm
----------------cut here--------------------
This wakes up the laptop 16 minutes (960 seconds) before the next 
calendar event.

To setup for this I had to make /sys/class/rtc/rtc0/wakealarm
be writable, and disable the systohwclock calls as per the mythTV 
discussion.  

In a proper setup, we would update the hardware clock and then set 
the wakeup alarm whenever we either start the reminder daemon, or
whenever we alarm something, or whenever a new alarm comes in.
