Just replying to share me experience, more information can only be good!
I installed yesterday, for the first time, Niresh's 10.8.2. The first time I always got a kernel panic on boot, so I tried again but this time selected a few more options. It gave me the same error at the end of install (couldn't restart and to use Startup Disk Utility). I just clicked restart and, just as before, the bootloader came up. I just put in -v and it booted straight away, right into the OS! And it always booted fine for every boot after this.
I had no QE though. My graphics card, and here is where it gets interesting, is the Nvidia Inno3d GeForce 9500 GT, 1GB RAM. So I tried a load of drivers, but it got to a point I'd messed around with so many kexts that it wouldn't even boot in the correct resolution, so I decided to reinstall. Now I can't install without getting kernel panics.
I researched on the internet and only then did I find that AMD and Nvidia don't mix. It seems my card shouldn't, but by a freak accident I got it working. Now I can't get it working any more, not unless I use -x to boot.
Now I swapped it with my Ati Radeon HD 4550 (also a problematic card...), but I can't boot this without kernel panic either. The only difference is that I can boot into -f and see my desktop, with the Nvidia I only got a load of multicoloured lines and dots.
To install, I've used all Niresh's own drivers. His AMD kernel and I used some Nvidia kext (I can't remember if it was Natit or the other one), along with GraphicsEnabler=Yes. Now I tried reinstalling using his package for Older Nvidia Cards. This time it recognised it not as an Nvidia card, but in Inno3D card and listed the model as 9500 GT. It picked up all it's specifications better too. So that seemed to be better, but it still gave me a kernel panic and wouldn't let me boot any way other than -x.
So someone DID manage to boot an Nvidia card without -x, just don't ask me to do it again though...
I'm seeing if I can have any luck with the Ati now, but it looks doubtful. I'm going to update to 10.8.4 first and then use the AMD kernel from this thread. Unfortunately I have Niresh's 10.7.3 V2 disc, but I can't get it to boot, it just hangs So that means I'm dedicated to getting ML working! Unless I just go back to trusty old Snow Leopard which seems to work with everything.
My CPU is an AMD Athlon 64 X3 by the way. If you need any more specs I can dig them all out for you. I built this PC ages ago for Windows. I had another custom built one that worked fine with all Hackintosh builds, but it broke. So now I fancy a challenge on this one.
