What we know about 10.6.5 so far...

• Intel Core i3 CPUs now identified in System Profiler and About This Mac... 
• Updated drivers for ATI and NVIDIA cards
• Two new ATI framebuffers: Nomascus and Orangutan for HD5xxx cards
• Adds support for exFAT file systems used on SDXC cards
• 10.5.0 Darwin kernel 

Most supported systems will not need to make any post-installation fixes, but here are a few points to be aware of. 

• Audio - The update will replace your AppleHDA.kext.  If you aren't using the ALC889a codec with Legacy889aHDA, you will have to reinstall the 10.6.2 AppleHDA Rollback using MultiBeast.  If you're using VoodooHDA, you will not need to make any modifications.

• USB - As of MultiBeast 2.4.1, EasyBeast has been updated to include USB Rollback, which enables full USB functionality on 10.6.5.  If you already have a system installed using EasyBeast, simply install the new USB Rollback option.  Download MultiBeast.

• Sleep enabler kexts are version specific.  Remove before installing the update.  

• iBoot 2.5.2 integrates the new 10.5.0 kernel and USB fixes for 10.6.5.  If you're having issues post-update, you can always boot using iBoot, then target your drive.  

• When using iBoot 2.5.2 as a rescue disk with 10.6.5, in order to have USB 2.0 support, you MUST have a USB 2.0 device plugged in at boot time.   Download iBoot.
