Ok guys - I have made the 'ultimate' kext configuration for the GA-965P-DS3 motherboard (this should also work for most other P965 chipset motherboards). Also - make sure you connect your HD up to the purple SATA ports (the JMicron ones, instead of the ICH8 ones). The disk read/write speeds are much faster!
This is it:
If anyone is struggling with making the ISO, I can upload this one. I've still yet to play with the version.plist files inside the kexts - in the meantime, you will need to boot with -v -f
(only when booting the retail DVD. After installation you can boot with just -v
Disk test with HD connected to ICH8 SATA port (orange one):
Disk test with HD connected to JMicron SATA port (purple one):
As you can see, using the JMicron SATA port improves disk test performance... I think this is down to which kext is used. IOATAFamily.kext is used for ICH8 (orange), whereas JMicronATA.kext is used for JMicron (purple).
