Dell D620 in 10.6.3 all working but update to 10.6.8 Wireless is missing

[spatz1115]

Dell Latitude D620 Intell GMA950

Apple BCM5751 Ethernet.kext working in 10.6.3, so that I can use wireless WiFi.

But When I update system to 10.6.8 from Apple Inc, Wireless WiFi then is missed, not working.

And I tried to reinstall AppleBCM5751 to the system by kexthelperb7, and reboot, It still did not work.and showed No wireless Card Installed.

 

What should I do then?
