Making an mbr boot usb on 8.2-stable

I recently changed my raid0 into two raid1's so I can have redundancy.
Getting a disk to boot was harder than I ever remember. Part of the
problem, my gigabyte bios locks up hard if there's a gpt usb drive
plugged in, not even scanning the memory. It seems to be a little known
problem. Some of the stuff I read on the internet mentions fdisk being
somewhat broken because of geom changes, and I couldn't get a usb disk
to boot that I made with fdisk or gpart. I ended up just dd'ing a
memstick image from freebsd.org onto a drive and booting that.
Annoyingly, the only one supporting zfs v28 is the 9-current image
judging by the timestamps.
I'm still wanting a rescue disk, and gpt is out of the question. I
don't want a cd because I want a full install and to be able to
periodically update it. I can partition the drive, install freebsd on
it, but it won't boot. I've tried gpart, fdisk, and sade but I can't
seem to be able to make it actually boot or even reach loader. I think
the furthest I got was boot1.
