Just to give an update, here is what I have done thus far:

1.  rpm -ihv kernel-2.6.14-1.1653_FC4.src.rpm
2.  rpmbuild -bp --target=noarch  /usr/src/redhat/SPECS/kernel-2.6.spec
3.  ln -s /usr/src/redhat/BUILD/kernel-2.6.14/linux-2.6.14 /usr/src/linux
4.  cp /usr/src/redhat/SOURCES/kernel-2.6.14-i686.config /usr/src/linux/.config
5.  rpm -ihv alsa-driver-1.0.10-42.rhfc4.at.src.rpm
6.  At this point, I wasn't sure how to go about the rpmbuild command,
so I just untared
/usr/src/redhat/SOURCES/alsa-driver-1.0.10rc3.tar.bz2 and copied the
portion that I needed into the kernel tree.
7.  I applied the patch to hda_codec.c
8.  /usr/src/linux/make modules
9.  cp /usr/src/linux/sound/pci/hda/*.ko
/lib/modules/2.6.14-1.1653_FC4/updates/sound/pci/hda/
10.  depmod
11.  reboot

Unfortunately, after all this I see that I'm getting "Unknown symbol"
errors when I try to modprobe the patched modules.  I did notice that
the patched modules were about 10x the size of the original modules,
so I tried running "strip -d" on them.  That didn't help.  I'm
guessing that step 6 is killing me here.  Any hints?
