Thanks for the info! Before we get crazy and start replacing core OS
functionality such as bootloaders, I want to give the guys over at FBSD
a shot at fixing this. I've taken your info here, and passed it on to
the folks who are working on 6-STABLE right now. Hopefully It's a simple
fix, and we can get it rolled into the final release :)
