I use NVRAM poweron on a PA-5 (K6, Super Socket 7).

Here is an excerpt of my program. It takes the parameter from VDR, does
some sanity checking and does something like this:

  restart -= 5*60;
  restart_tm = localtime(&restart);
  printf("Restart at:  %s",asctime(restart_tm));

  rtc_tm.tm_mday = restart_tm->tm_mday;
  rtc_tm.tm_mon  = restart_tm->tm_mon;
  rtc_tm.tm_year = restart_tm->tm_year;
  rtc_tm.tm_hour = restart_tm->tm_hour;
  rtc_tm.tm_min  = restart_tm->tm_min;
  rtc_tm.tm_sec  = restart_tm->tm_sec;

  printf("setting RTC: %d:%d:%d\n",
         rtc_tm.tm_hour, rtc_tm.tm_min, rtc_tm.tm_sec);

  retval = ioctl(fd, RTC_ALM_SET, &rtc_tm);
  if (retval == -1) {
    perror("ioctl(RTL_ALM_SET)");
    exit(errno);
  }

  /* Enable alarm interrupts */
  retval = ioctl(fd, RTC_AIE_ON, 0);
  if (retval == -1) {
    perror("ioctl(RTC_AIE_ON)");
    exit(errno);
  }

  printf("RTC Alarm: enabled.\n");

For the WOL: "wakelan" seems to work, but better google for wake on lan
linux.
