Here is my complete extensions folder for Toshiba Satellite L305-S5962 running OSX86 10.5.8 (leopard) from ideneb v1.6 lite. I used the voodoo kernel if it matters. All kexts have been edited, all devices are working (no DVD video playback) and system is rock solid.

Only thing you will need to install is the realtek USB WLAN utility, google for a download link.

Once installed configure your wired and wireless network controllers to static ip, then duplicate the service and set the copy to DHCP. This will enable DHCP. I think LAN has to be plugged in on startup to work.

The devices supported:
8101 Realtek LAN
8187 Realtek WLAN
GMA4500m/GMAX3100 graphics (DVD video playback isnt working)
Media Card Reader
USB
Audio
ect.
