i386 cannot address more than 4GB unless the kernel is built with PAE
mode enabled.  This isn't enabled in GENERIC for many (justified)
reasons.  If you have more than 4GB, you should be using amd64, so you
made the right decision there.

Boot loader problems are difficult to figure out/debug for reasons which
should be obvious.  I'm CC'ing John Baldwin here, who has experience
with BTX.  He might be able to shed some light on this.
