I downloaded the latest development drivers, lib, and utils (1.0.18rc3) and compiled and installed it again. Next I made sure that the /etc/modprobe.d/sound had the following line:
options snd-hda-intel model=imac24
and first I checked the gui tool called "PulseAudio Volume Control" from my "multimedia" section, and it crashes!
Next I tried the aplay somesound.wav file from the command line, it my Mac Pro sings!!!
I don't know what the PulseAudio issues are, but ... oh well!!
Next I checked that Amrok works using the alsa engine, and it does!!
If I plug in a headphone set, and I play music again it comes out of the MacPro speaker only, but no from the headphones.
Do you have a handle this, if you guys have some links for me to read, please send them my way!
Thank you.

You can create any file, typically, /etc/modprobe.d/sound or so.
Put the following line there
options snd-hda-intel model=macpro
Then reload the module, check the sysfs file
/sys/modules/snd_hda_intel/parameters/macpro to see whether the
specified option was really passed properly.
