Cannot install kext using 'OSX86Tools' in OS X 10.6.2
 

I've successfully installed and running Snow Leopard from Hazard 10.6.2 Intel-Amd DVD but I've a new problem. When I try to install any kext using OSX86 Tools I can't do it because all kexts appears grayed out as one I showed in the screenshot below, but I can manually install the same kexts using terminal ... Is OSX86 Tools not supported in OS X 10.6.2 ???? Any suggesstions ????
