Also, can you show me the appropriate portion of your grub.conf? I would like to see if maybe it is different than mine even though they are both pre-packaged installs. I had a machine with 2.6.20-2931.fc7xen, so I copied that to the machine in question, and it also only shows 3.1GiB for me. I compared the config files for that kernel and the one I was using, and they are identical (minus version and date comment lines), so that was as I expected, but it makes it less likely that my problem is a version problem and more likely that something else is haywire.
