Most modern motherboards supports the timer based automatic power on via BIOS settings. With linuxbios this is not(?) possible. There is a program for linux, called nvram-wakeup, to set the wakeup time in nvram or rtc. But especially for the K7SEM or EPIA boards a reboot is needed after it, so the wakeup settings can take effect. Does anyone know what the BIOS is doing what linuxbios does not? Perhaps it can be done in a program?
I believe it is just a matter of programming some real-time clock registers so an alarm will go off at a specified time, and setting up the appropriate southbridge or superio bits so that the board will wake up when the alarm is triggered. I doubt it even requires BIOS support at all. Though that can't hurt.
