The patch at 
http://people.freebsd.org/~ssouhlal/testing/kqueue-hooks-20050413.diff 
addresses the things you mentioned and introduces a MNTK_NOKNOTE flag 
to mount->mnt_kern_flag so that a filesystem can override the sending 
of knotes from the VOP hooks, in case it needs to do something 
filesystem-specific.

I will also send this patch to jeff@ so that he can review the VFS 
changes.
