I did.

Yes. but they are not very helpful ones.

ipoib HA is just a script that brings interfaces up/down.  Juding by the error
messages, we are trying to attach QP to a non-existent MC group.  You
implemented both the multicast module and ported ipoib to it, so ...

I did the backport for ucma, since it seemed no one else would bother.
The patch in question is
kernel_patches/backport/2.6.19/2_misc_device_to_2_6_19.patch
(and same for other kernels)

All I did, though, was revert the patch that updated ucma to new miscdevice API:
I don't however use ucma at all, and I only made sure the code compiles.

And, I have my hands full with IPoIB and SDP.

Please feel free to take over and replace this patch with whatever you find fit.
