I don't have one. I'm using the stock 2122 initrd, which is the same as
yours. And it works, despite all the insmods that fail, they are not
needed anyway.

What I'm after is a mkinitrd that will run and put all those bits into
an initrd init script regardless of whether the kernel has modules or
module support.

In short, loading modules isn't the only reason for using an initrd, but
mkinitrd acts as if it is.

Cheers
Steffen.
