Of course but it didn't help that I hope I didn't missed something all
steps I followed are as follows:

	# cd /usr/src/sys/powerpc/powermac
	# fetch http://people.freebsd.org/~nwhitehorn/atamodesetup.diff
	# patch -p0 < atamodesetup.diff
	# cd /usr/src
	# make buildkernel && installkernel

The symptom is still same with the previous that it looks no progress.
