Your out-of-tree modules are still compiled against your old config.  To 
fix this:

1) Correct your /usr/src/linux symlink, if needed, so that it points to the 
source tree of your running kernel.
2) Make sure the /usr/src/linux/.config file matches your running config.  
If you have no qualms about trampling the existing file this is easy 
enough to do with 'zcat /proc/config.gz > /usr/src/linux/.config'.
3) emerge module-rebuild
4) module-rebuild -X rebuild

That should make sure the modules installed are appropriate for your 
running kernel.

It could also be that your in-tree modules got compiled, but never 
installed over the old versions.  If that's the case, follow steps 1 and 2 
above, but then:
3) cd /usr/src/linux; make modules_install

That will compile the modules against the current config (if necessary) and 
install them under /lib/modules/$(uname -r) where modprobe expects them to 
be.
