How do I get audio working with versions previous to Red Hat Enterprise Linux 4 update 2 on the Precision Workstation 380n?

This system requires an audio driver not provided by Red Hat before Red Hat Enterprise Linux 4 Update 2. Dell provides the support for this driver, and the audio driver can be downloaded from the following url: http://support.dell.com/support/downloads/devices.aspx?c=us&cs=19&l=en&s=dhs&SystemID=LATITUDE%20PRECISION%20380&os=LIN4&osl=EN
