Awesome!
It finally got it working!
I can swear I tried the same steps before..but...
I installed all the graphic kext's from 10.5.1 and got CI/QE with terrible tearing, then I installed the Graphics update and before I restarted I installed the my modified kexts.
BAM! Full CI/QE, DVI and everything.
Thanks alot for all the help and support Firewalk and naquaada. I was really starting to give up but you guy encuraged me to keep trying!

Now my Leo install is as complete as my Tiger setup 8-)
And I made a serious backup of my current working kexts.

Thanks again.
