geli'd swap and core dumps

[Carl]

I would like to encrypt my swap partition like Pawel does on his 
company's production servers:

Does Pawel's method result in kernel panics having no functional dump 
device?

What are best practices for achieving encrypted swap and functional core 
dump recovery? Or are these mutually exclusive goals?
