heh!

FreeBSD's vm system is very different from NetBSD's, and I am not familiar
with it. The first and easiest thing to do is to check if the resource limit
for locked memory is set too low. Then hunt in the kernel sources for mlockall
and print the arguments it passes to the vm system. Anyway, the error is not
fatal, and amd should keep working after that.
