Should I install all these kexts at once or do the sound first, then reboot and then do the PS/2 ones?

Try an experiment, I think I read about this somewhere.

Go to /System/Library/Extensions and find ApplePS2Controller.kext. Right-click on it and select Show Package Contents. Find the Contents folder. Open that and find the Plugins folder. Open that and find ApplePS2Trackpad.kext. Delete ApplePS2Trackpad.kext.

Boot -v -f

On the first Reboot I was welcomed by a kernel Panic while it booted normally the second time. PS/2 Mouse is still not working. Idk, somewhere in verbose mode where the code is running across a black screen, I saw a message PS2Mouse.kext (or something similar, don't know exactly) could not be loaded and there was an error message in a bracket.

Maybe it's a permissions thing on PSMouse.kext. I know you performed the permissions operation.

Open Terminal

Type:  cd /System/Library/Extensions
Type:  cd ApplePS2Controller.kext/Contents/Plugins
Type:  sudo chown -R root:wheel PSMouse.kext
(give your password -- the cursor won't move -- just type the password and press <Enter>)
Type:  sudo chmod -R 755 PSMouse.kext

There, that sets the permissions on PSMouse.kext. Give it another boot with -v -f

After entering the password after the 3rd command, I got this: chown: PSMouse.kext: No such file or directory

Of course!!! The name is ApplePS2Mouse.kext. Use that in both places.

And finally, PS/2 Mouse Works! :D
Now, Only Issues that remain are:
1. Mac Appstore
2. Random kernel panics while OS is running.

1. App Store - all I can say is try it. But I'm serious about the ethernet thing. The prescribed way to get the App Store to work is to declare EthernetBuiltIn=Yes in org.chameleon.Boot.plist and to actually have your ethernet card recognized by OSX as the 1st network device. If it is recognized as 2nd device behind wireless, you can't access the store. Since you don't have ethernet, you may never be able to access the App Store from that computer.

2. Kernel panics - gotta take a picture of what it says and post it so we can figure out what is causing it - if it gives enough info to determine that.

1. App Store; Hmm, Any suggestions for a decent ethernet card that will let me run the app store flawlessly?
2. Kernel Panics: I'll post a picture here as soon as I come across a kernel Panic.

Ethernet card - what I would do is go to the Wiki for components under Lion and look for working ethernet cards and what they had to do to make them work. One series of ethernet card which has been around for a long time is the 8169 and Apple removed support for that from Lion. So the work-around is to go to 10.6.8 and get the kext out of IONetworkingFamily.kext and stick it into the Plugins folder of the Lion IONetworkingFamily.kext. It also depends upon whether you have PCI or PCIe slots in your computer.

Unfortunately, the browser is in the way of the good stuff. Performing a Google search gave all sorts of possible problems. Did you install the old driver for the wireless? One person speculated wireless could do it. Another had the problem and needed to reseat his RAM.

Yes, I installed the old driver for wireless. So, could that be causing the problem?

Maybe. Maybe not. If you leave the computer sitting and running for a while, will it have a random kernel panic or does it always happen when you are doing something? If it does it by itself, maybe leave it running for a while with the wireless dongle out and see if it still panics after a while. I can't answer. I don't have enough info.

This issue would generally occur when I am doing something, For eg: I was trying to download a wallpaper(as you could see above).

Does it only happen when you are doing an internet operation? If so, then there is a really good possibilty that it is the wireless.

In summary:

1. App Store: pretty sure you need an ethernet card
2. Kernel panics: if they continue and you can decide that they have something to do with internet usage, you might want to find a different dongle that has a newer driver. Suggest going to the Wiki, Lion components, and looking at the compatible wireless devices. There are several USB devices listed along with what it takes to make them work.
3. You should be able to boot without any boot flags now that booting is stable. But the minute something starts to happen, boot using -v so that the problem can be revealed.
4. Whenever you perform an OSX update (like 10.7.4 which is coming soon), it will install a kext in /System/Library/Extensions named AppleHDA.kext. To prevent a kernel panic, you must delete that kext before you reboot after the update.

Okay, I will purchase an ethernet card soon and continue. Till then, I'll manage with this almost working hackintosh. :D
