New system only running in 32-bit mode... why?

Hi all. I searched all around the forum and on Google for this answer, but couldn't find one.


I built a OSx86 box about a month ago. It's running fine, but I'm concerned that it's running in 32-bit mode, rather than 64-bit, given that the hardware supports 64-bit.


Intel Q9450 Core 2 Quad

Asus P5K Deluxe WiFi-AP

4 GB DDR2 800 RAM (other hardware too, but hard drives wouldn't affect this)


I installed Leopard 10.5.4 from iATKOS 4i with the vanilla kernel. The motherboard supports 64-bit, the CPU certainly supports it. The vanilla kernel should be running 64-bit on this hardware, but it's defaulting to 32-bit. I have confirmed this by running "arch" and "uname -a" in the Terminal, both report i386. I can't run any 64-bit applications. Chess, for example, crashes immediately upon launch.


Any thoughts? I've seen other OSx86 systems run in 64-bit mode, so I know it can be done.


Thanks, David.
