Still trying to get SL installed.
I hope theres's an expert who has some further useful hints on getting me going.
This is my last "success"

I'm using the latest myHack installer (1.0) and have all recommended kexts in /Extra/Extensions. I also removed the DSMOS from /S/L/E.
I tried booting with -v, -v -x, -v -f, -v -F and -v -s.
Only in case this hint helps: When booting with -v -s I see the prompt for some seconds before the system freezes with the same last line shown in the image.
Untill this screen I always had some kind of talkative errors I could use for further investigation but now I'm lost
Please help
