Stupid driver build/debug questions

New to the FreeBSD kernel and I'm investigating a driver problem
(wasn't sure what list this should go on).

I was wondering how to make a driver statically built instead of a
loadable module?  Is this an artifact of the driver source build or
the generic kernel configuration mechanism via options etc.?  i.e.
does a driver need to use something different than the
template make file to build a static driver.

What I am trying to do is break at attach time more easily than
stepping through driver_probe_and_attach()/driver_attach_child() until
the attach routine gets called.  I realize I can add a kdb_enter() but
I was trying to do this on a live system without rebuilding the kernel
(I understand this contradicts my first question but I still want to
know how to build drivers statically).
