Here's the list of artifacts that was created in 
/usr/src/redhat/RPMS/x86_64:

kernel-2.6.18-128.1.14.el5.x86_64.rpm
kernel-debug-2.6.18-128.1.14.el5.x86_64.rpm
kernel-debug-debuginfo-2.6.18-128.1.14.el5.x86_64.rpm
kernel-debug-devel-2.6.18-128.1.14.el5.x86_64.rpm
kernel-debuginfo-2.6.18-128.1.14.el5.x86_64.rpm
kernel-debuginfo-common-2.6.18-128.1.14.el5.x86_64.rpm
kernel-devel-2.6.18-128.1.14.el5.x86_64.rpm
kernel-headers-2.6.18-128.1.14.el5.x86_64.rpm
kernel-xen-2.6.18-128.1.14.el5.x86_64.rpm
kernel-xen-debuginfo-2.6.18-128.1.14.el5.x86_64.rpm
kernel-xen-devel-2.6.18-128.1.14.el5.x86_64.rpm

I was concerned when I didn't see something named
kernel-lustre-2.6.18-128.1.14.el5_lustre.1.8.1.x86_64.rpm

Checking the contents of both the original binary rpm, and the kernel rpm
I freshly compiled, they have different module directories:

/lib/modules/2.6.18-128.1.14.el5_lustre.1.8.1 vs
/lib/modules/2.6.18-128.1.14.el5

So may be I have to use an intermediate step and copy over the appropriate
config file from /boot. It left a question in my mind about whether the two
rpms were compiled from the same patched source, or whether there are 
additional
patches that should be applied as part of the process of creating 
kernel-lustre
rpm.

For the moment I'm ok, because with kernel-devel I've been able to compile
the drivers I needed. I'm still interested in the steps required to compile
a lustre-patched kernel though, in the pursuit of MB-sized i/o.
