In -CURRENT, yes.

As Giorgos says, with KDB--*if* you're using -CURRENT..  But first we
need to know what version of FreeBSD you're running.  If it's
-CURRENT, you should be tracking the current@ mailing list and asking
questions (after much research :-) there, not here.

=46rom the -CURRENT version of /usr/src/sys/i386/conf/GENERIC:

makeoptions	DEBUG=3D-g		# Build kernel with gdb(1) debug symbols

I'm a little confused where you got a configuration file that doesn't
already contain it.

This looks like something to do with building the ACPI code, not the
kernel itself.
