  On the versions of 2.6.14.2 that I've built for this, there are no 
modules.  The distro kernels certainly seem to have loaded modules for 
alsa.  The differences between my 2.6.14.2 which dies, and the one which 
works fine are _only_ (a) all g5 sound options built in | no sound, and 
(b) default keyboard | add AT keyboard in the input device support (the 
box is on a KVM switch).  Oh, and my configs are based on the 
g5_defconfig, but changed to all built in, and using the nvidia fb.

  Looking in the logs, the bad 2.6.14.2 has

kernel: ALSA device list:
   #0: PowerMac AWACS Rev 0

  lspci output attached, in case it isn't as expected.

  Checked for parport in my .config after your first reply, but it isn't 
there.
