OS 10.6.8's kernel doesn't support atom, so you have to get a custom built kernel.
Unzip that and drop that file onto the root of your hard drive, then boot from the SSD
Press shift key to get to the Chameleon prompt and type "recovery=yes", this boots into safe mode, and rename legacy_kernel in your root directory and change owner
sudo mv /legacy_kernel-10.6.8 /mach_kernel
sudo chown root:wheel /mach_kernel
(if you want to, mark the file hidden with "SetFile -a V" or "chflags hidden")
Reboot again, and this time boot loop will be gone, we are in OS X
