FWIW, on my Oneiric system, I did "modprobe rdma_ucm" and I see:
$ ls -l /dev/infiniband/ total 0 crw-rw-rw- 1 root root 10, 57 2011-11-07 10:34 rdma_cm
so with kernel 3.0 or newer, things work as expected.
(You can try this with a system that doesn't have any RDMA hardware)
As far as I know, this bug is only an issue on Natty and older.
