That would be a possibility. Although I prefer a solution without  
additional hardware. Also, I'm not sure, if it's good to constantly  
disconnect the board from power. Well, it's certainly better for your  
power bill, but maybe not for the BIOS battery.

I know that my BIOS supports setting a wake up time (you can set only  
the time, and it will wake up each day on that time). I've just  
discovered the /dev/nvram device and there is a program for Linux  
called nvram-wakeup, that uses the nvram device to set this wakeup  
time from the OS. One can then compute the next wakeup time (within a  
day) at every shutdown and write it to the nvram.

I have to see if this program also compiles/runs on FreeBSD ...
