modprobe: FATAL: Could not load module

These are just warnings. You can ignore them, or run these to lines to quiet down modprobe:

mkdir -p /lib/modules/2.6.24.4-linode8
depmod -a

modules.dep is a list of kernel module dependencies. It can't be loaded because it isn't there. It isn't there because you are using Linode's kernel, not the one from your distro.

mkdir /lib/modules/2.6.24.4-linode8 
depmod -a 

should fix it.

Edit: Gah - beaten to it by caker.
