Do I understand correctly that you compiled the alsa driver into the kernel, and not as a module? Because compiling it into the kernel would be a Bad Thing. Anyway, did you follow the instructions in the Gentoo ALSA Guide?

Did you emerge ALSA drivers too??? The Gentoo ALSA guide clearly warns that this is big mistake! Read the ALSA guide again. Make sure you have only <M> next to everything related to ALSA and your soundcard when you configure the kernel with menuconfig. This is really all in the guide, which I think you really need to carefully read again.
