I don't have the card, mine is GA-MA69-S2H, and my notes show:

Add hpet=disable to kernel options in /boot/grub/menu.lst (REQUIRED at
kernel Linux melusine 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17
01:58:03 UTC 2009 x86_64 GNU/Linux)

Un-comment MYTHWELCOME line in /etc/mythtv/session-settings

Create /usr/bin/MythWakeSet

#!/bin/sh

# inspired from http://www.mythtv.org/wiki/index.php/ACPI_Wakeup
# and https://help.ubuntu.com/community/MythTV/Install/WhatNext/ACPIWake
#
# MythWakeSet
#
# set mythtv wake-up time with UTC-adjusted time
#
# use: MythWakeSet date time
# ex.: MythWakeSet 2008-11-02 20:15:00
# See also 'man date' for date/time-formats.

# TimeZone, use +0100 for GMT+1
#TZ="+0100"
TZ=$(date +%z)

LOG=/var/log/mythtv/mythbackend.log

DATE=$(date -d "$1 $2 $TZ" "+%F %H:%M:%S" -u)
SECS=$(date -d "$1 $2" "+%s")

echo Running $0 to set the wakeup time to $1 $2 >>$LOG

if [ -e /sys/class/rtc/rtc0/wakealarm ]; then
  echo 0 > /sys/class/rtc/rtc0/wakealarm
  echo $SECS > /sys/class/rtc/rtc0/wakealarm
  echo "echo 0 > /sys/class/rtc/rtc0/wakealarm" >>$LOG
  echo "echo $SECS > /sys/class/rtc/rtc0/wakealarm" >>$LOG
  cat /proc/driver/rtc  >>$LOG

  if [ -e /proc/acpi/alarm ]; then
    echo $DATE > /proc/acpi/alarm
    echo "echo $DATE > /proc/acpi/alarm" >>$LOG

    echo "ERROR, Wakeup not set, no /sys/class/rtc/rtc0/wakealarm and
