I assume this means we change kvm_mkdb to get the symbols from the
kernel itself, and when it writes them to a file, we can then drop
them from the kernel? If so, I like this plan the best, and it
seems to solve all the problems. Is someone working on this?

Me, for a start. Even with as much stripped out of the kernel as
I can possibly manage, my 3/50 still swaps when I log in.
