Yes, we see patchless reported on our RHEL5U1 Opteron servers with

root at njxc4ad ~]# cat /proc/fs/lustre/version
kernel: patchless
[root at njxc4ad ~]# uname -a
Linux njxc4ad.usa.hp.com 2.6.18-53.1.14.el5_lustre. #1 SMP Wed

[root at ichpcsfsd1 ~]# cat /proc/fs/lustre/version
lustre: 1.6.5
kernel: patchless
[root at ichpcsfsd1 ~]# uname -a
Linux ichpcsfsd1 2.6.18-53.1.13.el5_lustre. #1 SMP Sun Feb 17
