Basically, for those unfamiliar, FreeBSD has a three stage boot.
First stage know just enough to load the second stage.  Second stage
knows enough about file systems to load a third stage.  Third stage
can load kernels, modules and pass information to the kernels.  Very
handy for thoese sorts of situations.  While the first two stages very
from arch to arch, the third stage is basically the same on all
architectures (although there is a md component to is that handles
processor specific relocation goo, etc).

Loading DSDT tables in FreeBSD is just another thing that the loader
can load before transferring control to the kernel.
