I can see several extra notifications on W2K and below.

You are now doing things different. Previously the test was to check if info is 
not NULL. Now you are only doing the test if info is NULL.

I think a broken() would be more appropriate here. So something like:

ok(info != NULL ||
    broken(!info && !registered_count), /* W2K */
    "got unexpected ABN_POSCHANGED notification\n");

Could you check the behavior on Win9x/NT4?

I guess Vincent Povirk can comment better on the patch as he wrote the initial 
tests.
