I'm assuming your previous kernel did not build alsa directly into the 
kernel image, so you probably have the alsa modules from the kernel in 
/lib/modules/ along with your new externally built modules (i.e. two 
sets of alsa modules in /lib/modules/`uname -r`/).

Firstly, did you run 'depmod -a' to update the modules database?

Search /lib/modules/`uname -r`/ for alsa to see if you have two versions 
(I'm guessing so). If from a package (like alsa-modules or alsa-driver), 
you could un-install the old drivers by removing this package. But if 
they were built as modules from the kernel, then you could just delete 
them (and re-run depmod -a) or you could rebuild your kernel (though 
unnecessary, just delete the modules).

If all else fails, on boot up you could rmmod the alsa driver and insmod 
the _full path_ to your new module..
