Perhaps check the permissions on the Extensions.mkext.  Honestly, I  
would just touch /System/Library/Extensions, but it sounds like you're  
not even getting to that point.

Are you running on ppc?  You could try thinning the kernel, but the  
booter shouldn't care about what architectures are present.  My guess  
is still that either the booter isn't being loaded properly or the  
booter can't load the kernel.

Make sure to always use the ditto command when merging roots into your  
system, it will preserve permissions and resources etc.
