Looks like you are using a 64 bit kernel. I am pretty sure I was able to run a server on a 64bit kernel at one point, but I don't recall for sure if I ever tried compiling on it or not. You could probably just use the info in the wiki to change your kernel to a kernel that isn't 64 bit and see if that helps.
You should be able to just install a different kernel by doing a command like this (from root):
Code:
apt-get install kernel-image-2.6-k7
Then, you will need to restart the PC. When it starts up, you will see options of which kernel to boot to. I think it selects any new kernels you install by default, but if not, make sure to try selecting the k7 one and see what happens. If it fails to load all of the way into Linux, you can just restart again and select the 64bit kernel instead. There are lots of kernels out there that you could try if the k7 one doesn't work.
