Yes on 64 bit systems you will see the maximum memory. On 32 bit you
need a PAE enabled kernel to get any more than 4Gig. If you have less
than 4Gig you may want to use the PAE kernel in any case because if you
have a relatively modern cpu it will support hardware Non execute
protection. On a non-PAE kernel you will see NX protection disabled or
such in dmesg.
