Still not sure what to do here. In my /boot directory I have this:

-rw-r--r-- 1 root root   88117 2009-02-28 02:28 config-2.6.27.19-5-xen
-rw-r--r-- 1 root root 6255788 2010-04-19 14:13 initrd-2.6.27.19-5-xen
lrwxrwxrwx 1 root root      22 2010-04-19 14:13 initrd-xen -> 
initrd-2.6.27.19-5-xen

In /boot/grub/menu.lst I have:
title Xen -- SUSE Linux Enterprise Server 11 - 2.6.27.19-5
    root (hd0,1)
    kernel /boot/xen.gz dom0_mem=2048M 
    module /boot/vmlinuz-2.6.27.19-5-xen 
root=/dev/disk/by-id/cciss-3600508b1001030364643393433300000-part2 
resume=/dev/disk/by-id/cciss-3600508b1001030364643393433300000-part1 
splash=silent showopts vga=0x317
    module /boot/initrd-2.6.27.19-5-xen

uname -a gives:
Linux test03 2.6.27.19-5-xen #1 SMP 2009-02-28 04:40:21 +0100 x86_64 x86_64 
x86_64 GNU/Linux

Inside config-2.6.27.19-5-xen have the lines:
CONFIG_XEN_PCIDEV_BACKEND=m
CONFIG_XEN_PCIDEV_BACKEND_VPCI=y
# CONFIG_XEN_PCIDEV_BACKEND_PASS is not set
# CONFIG_XEN_PCIDEV_BACKEND_SLOT is not set
# CONFIG_XEN_PCIDEV_BACKEND_CONTROLLER is not set

/etc/modprobe.conf.local has:
# hide pci card for xen passthrough
options pciback hide=(0000:0e:04.0)
options pciback hide=(0000:0e:04.1)
install mptspi /sbin/modprobe pciback ; /sbin/modprobe --first-time 
--ignore-install mptspi

So, doesn't this mean that the initrd being used is already configured
to use pciback as a module, so updating modules.conf (or
modules.conf.local on sles11) like I have should be enough?

Help is appreciated. Boss is breathing down my neck!

Thanks,
James
