OK. Thanks. Meanwhile I have recompiled the kernel (with aic7xxx.o built in),
and my system is up and running.
Wait, I have just seen Frodo's answer, which is "Yes". The plot thickens...

This is the standard RedHat setup. I believe it allows you to do a few things:
1. Doing fsck on the root partition (I don't think you can fsck a partition
while it's mounted, right?)
2. To have an initial file system before the module is loaded (??! that's what
I want, right?)

Nope. But putting in the RedHat CD and booting off it, running the whole
installation, IS EXACTLY what I call "reinstall system"!

I could get it to work in one of 2 ways:
1. Recompiling the kernel (which is what I finally did).
2. Reinstalling RedHat, which means doing the Redhat solution (either they
have a special kernel for aic7xxx, or they have a working setup to boot it as
a module).
