Which Planet CCRMA kernel is this? As you say, weird. You should take a
look at /var/log/messages and/or the output of dmesg to see if there are
error messages related to the audio drivers. What happens if you try to
load the soundcard kernel module by hand? (ie: "/sbin/modprobe
snd-intel8x0")

One possible scenario is that the wifi driver is using some hardware
resource that the soundcard needs as well...

The "sound comes back when booting into fc4's kernel" is to be expected
as you only installed the driver for CCRMA's kernel (and that's what is
apparently causing the conflict).
