[Julian Timm]

I have solved the problem with the automatic boot now.
Installing the r8168-dkms driver in the ltsp image fixes it! 

It looks like the r8169 driver that is used by default in Edubuntu on
Realtek network cards, sets a flag in the BIOS when shutting down
that tells the computer that it should start again when it was waked up by WOL
before.
With the r8168-dkms driver it works fine. :-)
