64BIt Snow Leopard

Well im waiting for my Wireless Network Card, and though ill look into 64bit Snow Leopard, ill be upgrading my Memory to 4Gigs with 4weeks, and didnt know if Snow Leopard needed to be in 64bit mode to see all my Memory. Found this here on how to automactic boot into 64bit mode.

edit this file:
/Library/Preferences/SystemConfiguration/com.apple.Boot.plist

Change this:

Kernel Flags


To this:

Kernel Flags
arch=x86_64

Done now reboot and you should be in 64bit mode. Please not you will need drivers with your hardware in 64bit mode, for me there was not issue. But when i get my New Network Card ill have to install the 64Bit kext file for it. Under 32bit mode it work out of the box.
