That procedure is not correct. cgz stands for .cpio.gz, so it is a gzipped
cpio archive. What you want to do is decompress the existing modules.cgz, add
your new module to it and make it into an gzipped archive again, something
like:
a)cp /work/modules.cgz /work/modules.cpio.gz
b) gzip -d /work/modules.cpio.gz
c) cpio -i -F /work/modules.cpio --list > mod-list
d) cpio -i -F /work/modules.cpio -d
This creates the file mod-list and the directory containing the modules.
This directory contains the driver files.
e) copy your module to this directory
f) You must add the added drivers to mod-list
Reconstruct the archive:
g) cpio -o < mod-list > modules.cpio
h) gzip -9 modules.cpio
You now have a usable modules.cgz.

In the pcitable file you make an entry with the module name, a descriptor,
and both manufacturer and device ID. These ID's are shown at boot by the bios.
Concerning the end of your subject line "Driver disk creation - where do I
find the .config file that was used to create the driver disk vmlinuz file?",
I think the kernel image is probably the same image as in the package kernel-
BOOT-##. You can find the standard config files in the source tree
(/usr/src/linux/configs). You most probaly need the kernel-BOOT config when
compiling modules for a driver disk. For your installed system you need the
"full" driver though. I don't know how RedHat usually handles this, but you
might have to post install the full driver by hand.
You can also check the kernel-BOOT package to see if there is a precompiled
module you can use.
Bye,
Leonard.
P.S. I wrote a kind of rough mini howto on how to edit a (net)boot floppy,
which is rather appropriate to this situation (if you know how to fill in the
differences). I'll send the question and my answer to it to you off list.
