I had a similar thing, no sound with any kernel after .18

My card is not the same as yours so my exact solution won't work for 
you. What I did was note which modules were loaded, then run alsaconf 
and let it do it's thing. Note which new modules it loaded and put 
those in /etc/modules.autoload.d/kernel-2.6

It appeared to be that the modules dependency information changed with 
my driver around .18 and the earlier config just didn't cut it anymore. 
Of course, I could also be completely wrong :-)
