I just wanted to post my success with getting 10.7.2 running on my Dell XPS 410.
Before I start, I want to say that I have a few different components than what came originally on the xps:
My video card is a Nvidia 9600GT 512mb which I got running with NVEnabler.kext (attached below)
My onboard ethernet NIC is DEAD. I am using a Netgear GA311 (realtek 8169 chipset)
Since this has been a very long, confusing process, I'm just going to attach the extra folder including the DSDT that I use minus the NVenabler since not everyone will need that.
I used a 10.7.2 retail file with ######. SATA is on AUTO-DETECT and remains that way. I recommend just having one hard drive (your target install HD) installed and no other drives installed for the initial install. I also recommend unplugging any USB device other than mouse/keyboard/###### jump drive.
And lastly, I recommend removing ALL PCI cards other than what is required (for me is only my ethernet card). I stress the importance of this as it was the only thing preventing me from working ethernet (and of course the last troubleshooting step I had made with SEVERAL attempts before it).
My only problems right now are that:
I have to boot from the USB drive still since my hard drive has a 4k sector size (a known issue). I'll attempt to fix this when I care/am bored.
I was having issues connecting to app store and icloud, but managed to fix it with this guide:

NVEnabler 64.kext.zip
