Also, did you install the new modules in the same directory as the old
ones? If so, the modules for the new kernel would have overwritten the
existing modules *except* in cases where your selections differ from the
earlier kernel. I.e., if you previously built agpgart (as an example
from the original post) as a module, but have it built-in to the kernel
now, the old module would not get overwritten. Those old modules will
cause depmod to spew "unresolved symbol" errors.

Of course, this doesn't really apply if you've changed kernel versions
along the way. Only in the case where you went from 2.4.22 to 2.4.22
w/SMP without changing the kernel version in any way.
