O.K.
after changing different options in patch_realtek.c
(mp3 option
imac24
imac9,1)

every option works,except imac24 configuration(no sound at all)
mbp3 works good(especially if imac9,1 is not patched into the kernel yet)
imac9,1 work's perfectly = its loud, plugging headphones(mutes
internal speakers),
microphone(don't know) I don't have any apps yet to test.(still need
to build them)

As for the main issue:
besides being an impatient drunk
I didnt follow the instructions at
http://cblfs.cross-lfs.org/index.php/ALSA_Utilities for
15-alsa.rules which was putting all of the created devices in
/dev/* instead of /dev/snd/*

Overall mbp3 options is good for now,
(this way people can enjoy there machines)
but the imac91.patch
works perfectly.

Thank you for helping me out.
