Help, System halt at this place. Could you please tell me why and how to solve?

System just halt here.... Almost every time... only 1 for 10 times succeed in normal booting.

Lucky enough, I can still get into the system using "-x"

Used Jas' 10.4.6 with PPF1 DVD to install

Installed Castillo and koverg for my X600M

And AC97 Driver for my ATI audio

Broadcom 80211 suport was selected during installation ( I know it cannot work on Acer because of the Radio problem, I just wanna see the Airport Icon)

Deleted AppleAirport2.kext ( Who tells me to? Forgotten)

And used a new Powermanagement.bundle to show the Bettery Icon
