Are we sure we are not talking about two different problems here.
I'm using RedHat and mkinitrd, in the initrd image there is already a
skeleton /dev tree that contains my real-root device. udev also exists
in the initrd image. I don't think any /dev device magic was necessary
for me too mount root.
It is not clear Chris which tools you are using on initrd, standard
Gentoo methods or a home brew setup ? What shell is calling modprobe ?
Can you confirm at what point you are seeing modprobe exit ?
* Immediatly (before device driver has detected hardware and reported /
registered its findings). This is the symptom I was seeing, but the
cause was incorrect shell handling.
* After detection but before device node creation.
* After device node creation.
