I finally got my wifi to work without the use of the -f flag.

Solution was as follows:

Reinstall ipc 10.5.6.
Selected only Nvidia Geforce 9800GTX NVInject only for my 9800GT
Selected Marvel Yukon 88E8056 for onboard network
Installed Ralink drivers which I downloaded from Ralink.com
(http://www.ralinktech.com/ralink/Hom...Macintosh.html)
After boot Ralink wireless utility came up and displayed available
SSID's. Chose mine, clicked on Connect and network started.
Immediately rebooted and upon reboot, wireless utility comes up to
allow you to select and connect.

I have a Ralink 2870, but there are drivers there for other Ralink devices.

I also got rid of my orange disk icons and now have standard MAC disk
icons. If anyone is interested, I will post a link for the kexts I downloaded
and the instructions to install them.

Only issue left is Time Machine keeps telling me
"The built in Network interface could not be found"
Still looking for a fix for this one.

Any help appreciated.
