This has been done before and i did have it implemented. The howto was on Nekochan and i've been trying to get that instruction back ever since.
Basically you need to start synergy with the help of the Xsession file and/or gdm file to get synergy working at the graphical login stage when the system has finished booting. Then after successful login with your keyboard and mouse mapped via synergy the current synergy will stop and a new synergy will start at your desktop.
If anyone has that howto do share it.
UPDATE:
I haven't found the howto but i have found copies of the relevant files on my build machine. This needs testing if this actually works but in any case i can share the files in here. I don't think it's wise to copy them 1:1 , you should prune them and compare them with your current files to find out what needs changing. For instance, my synergy server is called "link", you need to change that to your synergy server.
