Since I kept seeing many others with the problem of finding a Kext file on this LAN chipset, 881116, I did a Google on it and found this:

It was posted on Feb 2008 and seems to be newer than the other one that was made for Tiger OS X. I actually installed Zephy's 10.5.2 Rev 2. and it works just dandy except for the 1024x768 resolution. Rats... Anyways during installation of Zephy's 10.5.2 Rev2, I chose the nFORCE driver for the LAN naturally. It seems to detect the chipset but for some reason my Ethernet port shuts off during the first 15 seconds on seeing the Apple logo. I am about to try this kext and see what happens.

Well I did manage to get online. Unfortunately the kernal panics after just 2MB of data download. Yes currently I am actually using the Safari browser to make this post. Since I cannot download anything using this kext file I will have to revert back to using the older kext file which was made for Tiger OS X. If anyone has major success in downloading more than just 2MB of data, let me know what you exactly did.
