I have been trying to install SL 10.6.3 on my alienware with the following config -

Core i7 720QM @ 1.60GHz
NVIDIA GeForce GTX 260M
4.0GB DDR3 @ 1333MHz
IDT High Definition Audio CODEC
Intel(R) 82577LC Gigabit Network Connection
Intel 5300 AGN

Now I have tried to follow the other thread on the same config in the leopard section, after installing with a retail SL 10.6.3 with iBoot, just after a fresh install, I have my keyboard, touchpad, and sound working fine, with my processor recognized as Intel Xeon quad core, which I really dont't mind, But to make it boot by iteself I had to run Multibeast 1.1, now the official guide suggests installing 10.6.3 patch, which I do and then install multibeast, after the reboot sound is gone, and keyboard and touchpad stop working as well.

After trying to install various ps2 keyboard/touchpad kexts I fumbled upon myhacks, in this I can enable ps2 keyboard/touchpad and my keyboard and touchpad does start working, however I have not been able to make any further progress.

Also how can I keep the sound working after using multibeast or myhacks. I have not been able to find drivers for 5300agn. Also for my 260M if anyone has suggestion which kexts to use, since if I use kext from the other thread my card is recognized as 9800gs, btw I'm able to run my system on its max resolution i.e. 1920x1080. I really want to get the sound and wifi going.

I have a usb wifi adaptor its a Netgear WG111v2, I have found drivers for it, it even shows wifi networks, however even after connecting, I can't access internet on the device.

I would appreciate any help/suggestions.

Bump, c'mon people, need some helping hand here..
