Ok. I erased /System/Library/Extensions* and copied it from DVD (at least dvd boots in gui all the way). Still no boot in GUI for setup completion.

Have anyone a clue for the reason of such behaviour? I can pastebin required system logs.

Thanks.

P.S. I saw a record in HCL that someone make a nice hummer kiss for my mobo and Leo... I wish to talk to that person...
