Cant force SL into 64bit kernel - 2009 mini

[KyleAwesome]

/Library/Preferences/SystemConfiguration/com.apple.Boot.plist

Locate:

<key>Kernel Flags</key>
<string></string>

Change it to:

<key>Kernel Flags</key>
<string>arch=x86_64</string>

I'm having some trouble booting into 64bit kernel. I have a 2009 mac mini with 64bit EFI, 64bit Proc, 64bit kernel... I've tried holding down 6+4 on boot, I've used the app 32-64 kernel selector, and tried manually updating the plist. still shows 32bit EVEN though the plist says its 64bit.

Any ideas?

Don't boot to 64-bit kernel. You get absolutely nothing from that

I purely wanted to try. I dont have non-64bit capable devices hooked up to the machine. Curious, you know...

Quick question.

Not a pro when it comes to kernels/32-bit vs. 64-bit. Why is 64-bit windows (64-bit kernel I assume?) such a big deal where as OS X not so much? Is it because there are already applications on the Windows side that already benefit from it and OS X doesn't have a strong support yet? Any answers/clarification would be greatly appreciated.
