My gut instinct with this is that you may have a corrupt installation usb, or something else corrupting - does the 'report crash' section appear in the same place each time? Have you tested the hardware (check filesystems with disk utility, test memory with memtest86+, run a torture test with prime95/mprime to ensure the cpu is stable etc). If your system passes all of those tests I would test the USB, or even suspect the source data - did you get your copy of OS X legitimately from the app store? I'd likely attempt to recreate the USB, or try another one, or internal disk partition. If all that failed I would try various USB ports, if that failed, I would start to suspect the source data. I have the same motherboard as you and I had no such problem, though I did have a problem with a bad USB stick on my first attempt, the second USB stick worked flawlessly.

Chameleon is installed to the boot sector, partition header, and filesystem of the disk/partition you target to install OS X on. I could make it optional if anyone else feels this would be a good option to have.

Please post your questions regarding UEFI in the appropriate forum category, I will respond there.

Where it is hanging is not the realtekR1000, it is hanging at graphics init. Have you tried to force VESA mode by removing the ATI* / Radeon* kexts? From the myHack Guide: This would be the other option, but given the fact you just want to get 10.6.8 running quickly to grab ML from the app store and then reinstall with ML I don't see any reason to go through the trouble of finding that update and then extracting the graphics extensions from it - force VESA mode, get appstore working, prepare your 10.8 myHack OS X Install Disk and install.

I don't use RAID on boot volumes, I use a single SSD for my OS partition and I use software RAID1 for my data storage. This is what I suggest to basically everyone. Hardware RAID is only good on enterprise level builds with very expensive controller cards. It has some disadvantages when used on a consumer level and no advantages, which is why I prefer to use software RAID.
