I will. Unfortunately I have to compile some things first, so I'll get
back to you on that.

Even after shrinking the partition to exactly 1600 sectors and using
!Apple_Bootstrap, it still doesn't work. Output of `gpart show' below:

When I boot my system, I first get the classic folder icon with the
question mark in it. After a couple of seconds, I end up in the Open
Firmware console.

Thanks for your help so far!
