Happy to try but I have "no clue" as to were to start. If you could give a couple of pointers on what to do...
(btw, removing NVDAResman, adding NVEnabler and enabling GraphicsEnabler seems to have given a reasonable boost but still not fully accelerated).
Ok so I am looking for the 8600M efi string but cannot find it. Someone has a post/url I can get it from?
Then I assume its a case of setting it via EFI Studio?
Will need a backup plan if all fails.
I'm in the same position as you regarding the graphics. I can perhaps help with the backup plan.
The easiest solution I know of is to use an external USB drive, to clone a copy of your OSX installation to it and to make it bootable. This way you can (if you're paranoid about making mistakes) remove your hard drive from your laptop and boot it only off the backup image on the USB drive and start experimenting. If it breaks, simply restore the image again using your working laptop.
The basic procedure:
Obtain a copy of Chameleon RC4 and Netkas's PC EFI 10.6. Create a folder somewhere on your drive and unzip the archives there. You'll need it later to make the USB drive bootable.
Log into your Hackintosh, free up as much space as possible before starting (move data elsewhere). Empty the Trashcan. Then start Disk Utility and perform a Repair Disk Permissions.
Reboot the laptop off an installation DVD, (I think in my case I used IPC 10.5.6 or perhaps Hazard's one, it doesn't really matter which you use).
Instead of installing, start Disk Utility. Now's also a good time to attach the external USB drive which will be reformatted / overwritten. Format it to MacOS Journaled.
Select your Hackintosh system drive in Disk Utility's lefthand pane. Click on File, New, Disk Image from Disk0. You can give it whatever name you like, the "save to" location should be the USB Drive.
Image format - choose compressed
Encryption - None
This will take some time to complete depending on the size of your installation. (Better to free up as much space as possible before starting).
Once this is done remove the Installer DVD, boot your working Hackintosh system again. Copy the Hackintosh disk image on the USB drive (the dmg) to your Hackintosh desktop. (You'll obviously need enough remaining space on your local drive for it to fit.)
Now start Disk Utility again in the running system. Click on "Images" in the top menu bar, select "Scan Image for Restore". This will take some time to complete. Once it's done, click on the "restore" tab and click on Image and select the image you just scanned.
For Destination, select your USB drive, drag it into destination. Leave "Erase destination" ticked. The restore operation will overwrite your USB drive with the image you created before. Click Restore.
Once this is complete you'll need to install Chameleon on the USB drive to make it bootable.
Open a Terminal. Type df -k
It should give you a clue what disks are on your system, for example:
/dev/disk0s1 (local harddrive)
/dev/disk1s1 (USB drive)
disk0 should be your local drive, disk1 should be your USB drive.
cd to your chameleon installer files and install boot0 to the MBR of the USB drive:
sudo fdisk -f boot0 -u -y /dev/rdisk1
Install boot1h to the USB drive bootsector:
sudo dd if=boot1h of=/dev/rdisk1s1
Copy Netkas EFI boot (NOT the Chameleon one) to the root of your USB drive:
sudo cp boot /the_path_of_your_USB drive (look for whatever /dev/disk1s1 is set to)
Shutdown Hackintosh, remove internal harddrive, reboot with USB drive attached. It should now boot from USB and run the OS off the USB drive. If anything gets messed up during experimentation just restore the image again using the same procedure.
