I have found that I can do a totally fresh install of Lion (with a lot of trial and error priorly performed) by doing the following (you will still need a working install of Snow Leopard):
Follow this guide to create a rescue disk:

I did it using a flash reader and MicroSD card (65MB).
Once done, copy your /Extra folder along with your DSDT.aml file to the root of the rescue disc. This rescue disc is what allows you to boot into Lion after fresh install otherwise you will experience a Kernel panic. This rescue disc is very useful for later accessing the Install partition (which I leave on my drive permanently) or if I get a kernel panic.
Incidentally, my motherboard does not have a patched DSDT AFAIK (it is a DFI Lanparty DKP35 T2RS) but I did extract and create a vanilla one using DSDT editor. Without the DSDT on this rescue disc Lion will not boot. You MUST extract the DSDT and compile it from Snow Leopard AFTER running the Apple combined update (3.6.8) and running Multibeast 3.8 or 3.9 Snow Leopard edition.
Follow tonymacx86 Xmove+multibeast guide to get the Lion install extracted and ready for installation.
I did the install by partitioning my boot drive (from Snow Leopard) with the 8GB method. After Lion extraction you do this by running Xmove and selecting the 8GB partition for install. Boot from Chameleon, select the Lion installer drive/partition and before you start the installer go to the Utilities at the top and run disk utility. Delete your Snow Leopard partition, create a new one and name it Lion or whatever you want and apply. Close disk utility and continue with installation. Select the Lion partition and install. This process is much quicker than updating!
At the end of the install, you MUST do the first boot into Lion using your rescue disc. Once there install Multibeast as usual and enjoy a freshly installed Lion. Keep your rescue disc intact and safe.
I had no success using Multibeast V4 (designed for Lion) on my PC so I used V3.9 which works perfectly. However, V4 does work fine on an Asus P55-Pro motherboard using a patched DSDT. I have done this fresh install successfully on the above 2 motherboards, and as mentioned when I need to the fresh install is MUCH quicker and cleaner than an update. I am also confused with Multibeast V4 when it puts the kexts into system folders instead of the /Extra folder. This makes repair far harder than simply keeping them in the /Extra folder.
Big thanks to tonymacx86 for his incredibly useful toolsuite!
NOTE: I take NO responsibility if the above does not work for you. Back up all your data before trying this because you WILL lose your Snow Leopard install. I did this from a fresh drive and had not data so I did not care if I had to re-install Snow Leopard. Do at your own risk. Feel free to ask me any questions (I just included the basics but I have a lot more to share if needed, I learned a lot in the last 6 days about Hackintoshes including how to restore a bad boot
