iMac Graphic FW Update 3.0 is NOT for the generation of iMac that suffer this issue (early 2009 with GT120 o GT130 Video Cards) and this thing is very frustrating because Apple did NOT help all these users after all these years putting out a stupid right software update. That one you mention is useful for imac younger than the model we're talking about. It's Embarrassing thinking that these expensive  iMac (they costed more than 2000 bucks)  become dead stuff at the moment you  upgrade from 10.6 to 10.6.3 and above... something in the new code breaks the "equilibrium" of this damned video card and your iMac that one hour before worked in excellent way now crashes anytime. Always kernel panic: ALWAYS
