Label on the box and laptop itself says I've bought Core i5 M450 2,4Ghz, but I was surprized to see i5 M460 2,53Ghz :-)
busratio=19 key is needed to start 10.6.3 installation, and is supported fully after 10.6.4 or 10.6.5 upgrade.
Connexant HD sound works great with latest VoodooHDA 2.7.2 - all inputs/outputs work flawless.
GeForce GT330m 1Gb can be enabled via DSDT patch or GraphicsEnabler=1 key in boot.plist . Then you can install latest NVidia drivers from their official site, and then Cuda driver.

WiFi was replaced with Atheros 9285, no bios editing was needed, chip is supported with 10.6.4 kext.
Synaptics trackpad is working flawless with AnV modded VoodooPS2Controller.kext
Updated to 10.6.6, by using ##### 3.0 and removing AppleHDA.kext before pressing "Restart".
