I've heard on and off that the X1550 supports QE/CI with a few hacks/modifications.

I've tried ATY_Init but it never worked. Trying EvoEnabler now, I've seen a post saying the X1550 and the X1300 use the Caretta codename/framebuffer.
And the hex number is 7187.

In some cases I cannot boot into 32-bit mode but I can use 64-bit mode.
Also I have to use latest IOPCIFamily because Natit is complaining about it.

Attempt 1: EvoEnabler using the Caretta Framebuffer.
32-bit mode: Nope. Just sticks at evoenabler: Probing
64-bit mode: Managed to get maximum resolution (1440x900 for my HP w19ev monitor). No QE/CI.

Attempt 2: Natit
32-bit mode:This is the opposite of above. I get maximum resolution without QE/CI, but not under 64-bit mode.
64-bit mode: Nope. Natit is 32-bit on here.

Attempt 3: Natit + ATIRadeonX100.kext (Modded)
I did not try 64-bit mode since my wireless adapter requires 32-bit mode.
It loads, but then it goes blank.

Use the tool found here to dump the framebuffers and post output:

Then we can go from there. 32 bit mode will be the only one that will work since the Mac that had that generation card was 32 bit EFI.
