About HD 4350 GPU

hi tony
There is a detailed instruction in our GRAPHIC CARD DATABASE to install ATI HD 4350 card in lion it works nice But there says about a command that is
"After success loading with full acceleration, to make Lion boot faster with cache, type this command inside terminal , because if we use KernelCache option on org.chameleon.Boot.plist value into "Yes" it will not work."

Which is that command, can you help
