Hi!
Thank you for your suggestions! Freezed-and-stopped boot solved.
Strange, but it was something around the video-drivers because after I have moved all the video-kexts (AppleIntelF*, AppleIntelH*, ATI, GeForce, NVidia) from S/L/E, the boot process are stabile and goes speedy.
A few words about the HD-audio. Somebody says at the newest VoodooHDA kext is OK. Yes and no. My experience is at with the Voodoo-kext all the In-/Outputs comes up but the sound quality is poor. Very poor.
I have found somewhere on this site a version of AppleHDA that works. Only the front panel stereo output, but without distortion.
My final (but maybe the biggest) problem is the HD4600 video. I can not make it work. GraphicsEnabler=Yes/No, IGPlatformID=nothing-works. I can use multi-monitors on DHMI+DVI (1080p) but no 3D acceleration... And of course I finally deleted the video kexts to reach stability.
So now this is the situation:
