I have a kernel that needs to have early hotplug calls to load
firmware. I just rolled my own simple hotplug scripts to only address
that issue and have not had a problem since. The mdev in busybox that
is in the gentoo initramfs didn't seem to be able to handle it, so I
just made my own scripts. In my case I needed QLogic firmware so root
could be on FC.

FWIW, it is a real PITA to not be able to build a monolithic kernel
that can bring up root on its own. I will stipulate that I am an old-
school guy that likes monolithic kernels, but I do feel that
something has been lost. Yes, I am aware of the reasons for the
change, else I would have written something when I was fighting the
battle, but I still don't have to like it.
