This is the audio driver: http://www.asus.com/support/download/item.aspx?ModelName=P4P800%20SE
The audio driver there looks like source for ALSA, which is a standard part of the Fedora kernel. Do you know exactly which driver module is supposed to support your motherboard?
and I have installed this kernel, for support my samsumg magiclan 2300p wireless card, via ndiswrapper: http://www.linuxant.com/driverloader/wlan/full/downloads-fc3-kernel-i686.php
The source is also available at that site: http://www.linuxant.com/driverloader/wlan/full/archive/fc3/kernel-2.6.9-1.681_FC3.stk16.src.rpm.zip
