nVidia has precompiled packages for RedHat if i'm not mistaken. When you really want to compile it yourself, I sugest to build your own kernel (with a vanilla source tree) as well.
The problem is that when you build your own kernel, ac97 won't be compiled with it by default. I worked around this by including via686 sound support as a module (any other AC97 driver is possible as well)
This will place a module ac97codec.o in /lib/<kernelversion>/kernel/driver/sound/
