insmod 3c59x works, modprobe 3c59x fails !

Now why would this be the case?
I just upgraded my kernel from gentoo-2.4.19 to vanilla-2.4.20, and in so doing I compiled my 3Com Corporation 3c905C-TX/TX-M [Tornado] NIC as a module, as I usually do.
As a result, after make modules_install, the driver (3c59x.o) was sitting happily in /lib/modules/2.4.20/kernel/drivers/net/. And "modinfo 3c59x" gives correct output.
(I also ensured /etc/modules.autoload still had the "3c59x" entry before rebooting)
However, when I rebooted, the network start failed (and hence all the net-related daemons) because, I found, that the module "3c59x" was not located. When I tried

# modprobe 3c59x

.. I received

modprobe: Can't locate module 3c59x

.. even though modinfo could! Why oh why oh why?

"insmod 3c59x" works fine. But then I have to start all my net-daemons manually!
Now I am compiling the 3c59x into the kernel (not as a module) in the hope that it will work.
But this is a DIRTY SOLUTION, and I SHOULD NOT HAVE TO DO THIS. Surely?

Others may have had this problem:

Just to confirm, compiling the 3c95x driver into the kernel worked OK, allowing the network interface to be activated at boot time.

So the question remains: why does "modprobe 3c59x" fail?

Try tossing a depmod -a command in after you make modules_install.

It looks like your module dependencies aren't getting re-built, so "modprobe" doesn't know what to do. Is
