I am currently running 10.5.7 Retail on an ASUS P2-5945G with everything working.

Using Chameleon 2.0 RC1 with 11 kexts.

Steps to install:
1- Downloaded and booted from iDeneb 1.4 DVD. I couldn't boot from the retail DVD.
2- Formatted 3 partitions Mac OS Extended (Journaled) with GUID partition table.
3- Installed iDeneb to second partition.
4- Booted into iDeneb, installed Chameleon 2.0 RC1 on first partition.
5- Loaded kexts into /Extra/Extensions on first partition.
6- Used disc utility to restore Retail 10.5.6 DVD to 3rd partition.
7- Booted and chose to start from 3rd partition using Chameleon.
8- Installed 10.5.6 Retail on 1st partition.
9- Booted into 1st partition (retail) and deleted other partitions, resizing first partition to full.
10- Downloaded and installed 10.5.7 update. Rebooted.
11- Fully functional retail install.

Bios Settings (ASUS P2-5945G)
- Advanced > CPU > Set Execute Disable Function to ENABLED
- Power > Set Suspend Mode to S3
- Power > Set ACPI 2.0 Support to YES
- Power > Set ACPI ACIP Support to ENABLED

Kext Pack:
My kexts can be found attached to the thread on insanelymac 10.5.7 Retail installed on Asus P2-5945G | Everything working including GMA 950 (0x2772) - InsanelyMac Forum

If someone needs them posted to rapidshare, just ask.

NOTE: AppleIntegratedFrameBuffer.kext must go in /System/Library/Extensions because Chameleon 2.0 RC1 can not load it.

NOTE: I do not have kexts for SATA devices

GMA 950 Fix (Intel 82945GZ Devide ID 2772 Revision 0002):
To get full resolution and hardware exceleration, use the framebuffer from 1.5.1 with the stock 10.5.7 drivers. The trick is that if you put it in Extra/Extensions it will not be loaded by Chameleon, you must replace the one in /System/Library/Extensions for it to work. With the 10.5.7 drivers and 10.5.1 framebuffer I'm getting full support with artifacts limited to certain applications.

I tried Dr. Hurt's DSDT.aml patcher but it doesn't work with this motherboard, so after lots of searching this is the only solution I could find.

ADI AD1988b Fix:
Use the kexts in my supplied file.
