this Apple's link is misleading. Type of processor alone does not describe the "bitness" of the OS. E.g. Core 2 Duo Macbook Pro can well be running 32-bit OSX 10.6. To find this out exactly, click "Apple"->About this Mac->More Info->Software. You will see something like the following:
System Software Overview:
