You can download a patch from http://www.cs.rice.edu/~alc/amd64_kvm_6GB.patch that increases amd64's kernel virtual address space to 6GB. This patch also increases the default for the kmem map to almost 2GB. I believe that kernel loadable modules still work. However, I suspect that mini-dumps are broken. I don't plan on committing this patch in its current form. Some of the changes are done in a hackish way. I am, however, curious to hear whether or not it works for you. Alan
