Why would I want 640MB of swap?
Actually thinking more about it, the only thing that needs to be saved in a kernel panic is the kernel itself and its data structures. Saving a whole snapshot of ram probably wouldn't be terribly important. Most likely the kernel + structures will always fit into swap even if its smaller than physical ram. I should go look at what exactly FreeBSD saves in a crash dump.
