And of course an hour after I sent this message I got a working RHEL 6 kernel (2.6.32-131.17.1.el6.x86_64) on my RHEL 5 system, replaced OFED to get XRC support, rebuilt Lustre (1.8.6-wc1) and am now testing this configuration. It's not the prettiest setup in the world but it seems to be working so far.
