The alsa install went very smoothly for me. You might look at the 
setting up alsa and Red Hat section of the docs at www.mythtv.org 
because I wrote them based on my experience getting alsa going on this 
board and red hat. Below is the relevant section of my modules.conf. It 
is embarrassingly  unorganized, and some may not be "correct" but it 
works for me!

To get this board working I first built fresh rpms (because I was using 
an updated kernel) like this:

as root:

# rpmbuild --rebuild source_rpm_name_here

then pay attention to the last few lines of the build process. That 
will tell you the path to the output binary rpm. Usually something like 
/usr/src/redhat/RPMS/i386/

go there.

make sure you don't have a previous version of that rpm installed

# rpm -e binary_rpm_name_here

then install your freshly compiled rpm

# rpm -i new_binary_rpm_filename_here

I installed the nforce platform combo drivers, the nvidia kernel driver 
and the glx package.

  I also commented out the line
Load  "dri"

and changed

Driver      "nv"

to read

Driver      "nvidia"

in /etc/X11/XF86Config


finally it tuned off usb legacy support in the bios to get usb working.
now everything on that board works perfectly.

Best of luck,
cedar
