The problem might be that you're mixing 2.6.18-128.* with 2.6.18-164.*, if you
stick with versions 2.6.18-128.* you should be fine.
At least this is working for our patchless clients:
[root at client001 ~] # rpm -qa | grep -e lustre -e kernel | sort
kernel-headers-2.6.18-164.11.1.el5
kernel-xen-2.6.18-164.11.1.el5
kernel-xen-devel-2.6.18-164.11.1.el5
lustre-client-1.8.1.1-2.6.18_164.el5xen_01
lustre-client-modules-1.8.1.1-2.6.18_164.el5xen_01
We're using virtual machines so lustre modules are compiles for
kernel-xen-2.6.18-164.el5 but those exact same modules worked fine with
kernel-xen-2.6.18-164.6.1.el5 and kernel-xen-2.6.18-164.9.1.el5 and now with
kernel-xen-2.6.18-164.11.1.el5
