Sigh.... If you are running stock freebsd-7.x and you have correct
include files kqemu should just work.

Ok, try this:

uname -a				# this should show 7.2 or some 7.x
grep FreeBSD_version /sys/sys/param.h	# this should show a number > 700044
pkg_delete /var/db/pkg/kqemu*		# blow away any kqemu
ls -l /boot/module			# this should have no kqemu.ko
cd /usr/ports
make -DSUP_UPDATE update		# or however you update your ports tree
cd /usr/ports/emulators/kqemu-kmod-devel
make clean
make install
kldload kqemu	# this should succeed

If this fails, report
uname -a
grep SCHED /sys/amd64/conf/GENERIC 	# if that is what you are running
ls -l /usr/include/sys/param.h /sys/sys/param.h
ls -l /usr/ports/emulators/kqemu-kmod-devel
find /boot kqemu.ko
