Just to let you know, I've also met this problem (on another distro),
and did not know about this bugreport until now.
So I've done another workaround: modprobe already parses /proc/modules
to check whether the modules needed are already loaded, and this file
also shows us the state of the modules, being "Loading", "Live" or
"Unloading".
With my patch, modprobe waits until the needed modules come out of the
"Loading" or "Unloading" state.
