It seems to all come in with the main driver for the ALC650.  And it 
works pretty good once i got it figured out.  Everything but the 
bt878 audio, which is so far down the s/s+n isn't more than 30 db.

c0164376 isn't a label, but its in between these two in the System.map
c0164340 t prune_dcache
c0164500 T shrink_dcache_sb

But thats all I can deduce from here.

I CC:'d this back to the list in case those two labels might mean 
something to someone else.

Thanks
