Thats correct.

What has your experience been with building your own lustre rpm's from source using a different kernel? Do you still have to patch the kernel? I am also thinking about installing sles 11 sp1 and just building the lustre client rpm's from source. Not sure if it is required to patch the kernel if I use the most updated version provided my sles 11 sp1.
No. Lustre client kernel modules are self-contained aka "patchless" clients. Its been a while since I made the RPMs, but I found this laying around:
./configure --disable-server --with-linux=/usr/src/linux-2.6.22-pfm-xeon --with-o2ib --enable-quota --disable-readline
Then I believe 'make rpms' does the right thing.
Now that I said how easy it was, there is a caveat. Now, there may be issues with specific kernels, but this worked for us. The linux-2.6.22 kernel is a kernel.org kernel with pfm patches (performance monitoring) and this kernel also has a NDAed patch from AMD because there are bugs in the CPUs and the patches are workarounds for the bugs in the CPU.
It works for us, YMMV.
