If you want to use the drivers provided by the alsa-driver ebuild, you
need to disable alsa support in the kernel:

Quoted from http://www.gentoo.org/doc/en/alsa-guide.xml 

"If you have compiled your kernel and want to use alsa-driver, please
ensure the following before proceeding, else alsa-driver is likely to
fail. The next code listing gives you one way of performing the
checks.

   1. CONFIG_SOUND is set. (Basic Sound support enabled)
   2. CONFIG_SOUND_PRIME is not set. (In-built OSS support disabled)
   3. CONFIG_SND is not set. (In-built ALSA support disabled)
   4. /usr/src/linux points to the kernel you want ALSA working on."

If you use the kernel ALSA support, even in module form, you cannot
use the alsa-driver ebuild.

HTH,

Matt
