Thanks! I went with option 1 and added a line to the postinstall
file to copy the .ko file out into the kernel drivers directory. It
seems like the driver then makes it into the initrd regardless of if
I actually include my driver in the -n line or not.
Is there a difference in the behavior I should be seeing by using
the -n flag? I actually ran a recursive diff between an extracted
initrd where I listed the driver with -n and without, and there were
no differences.
Just trying to understand this functionality a bit better :-)

Where does xCAT look for the "replacement" drivers? If you
specify, for example, "genimage -n foobar", where would one then
place the foobar driver for xCAT to pick it up and place it in
the image for you?

But one think you need to know that if you specifying the -n,
it means replacing the default driver list instead of
appending. That means you'd better add the default ones in the
-n with your specific drivers.
The default drivers for rh x86_64 is: tg3 bnx2 bnx2x e1000
e1000e igb mlx_en virtio_net be2net

I was speaking more towards adding drivers to a stateless
image, for example an updated tg3 nic driver.
You can of course just unpack the initrd, manually add the .ko
file in, and repack it, however I was wondering if there is a
better supported way to have xcat automate this piece.

Adding extra kernel modules
Hi all,
What is the proper "xcat-supported" way of adding extra
kernel modules
into a stateless Linux image? I have found some fairly old
docs stating
to copy them to /opt/xcat/share/xcat/netboot/$OS, list
them in the
genimage "-n" option, and xcat will pick it up and copy it
into the
image/initrd for you, but I have been unsuccessful in
getting that to
work with my 2.6 setup.
