This indicates that the modules and the kernel aren't matched.  IOW, you 
apparently compiled the new kernel but failed to compile the matching 
modules, so it's trying to use the old ones, which don't match the new 
kernel, so it won't load them.

Even if it's the exact same kernel you compiled, if you change options, 
particularly something as big as SMP, you'll need to recompile the kernel 
modules as well.

Also note that if you use an initrd/initramfs, you'll need to redo it, 
loading the new modules as appropriate into it as well as placing them in 
the normal /lib/modules/<kern-ver>/ dir.  I don't run an initramfs/
initrd, so have never learned the technical intricacies thereof, but 
wherever it's trying to load them from, you don't have the right ones 
there for it to load.

One way or the other, with or without the initrd/initramfs, the kernel is 
trying to load modules that don't match the kernel, and failing.  Correct 
that, and you will have fixed at least that problem, altho it's possible 
you'll then have others to fix as well.
