Sorry to be obtuse, but I do not think that this bug has been fixed.

Reasons because this is what I tried first when I encoutered it.
The binary compiles, but it fails to run/black screen/kernel panic (any of those may happen).

I was running a vanilla 2.6.31 kernel with rt11 patches though, I
haven't looked into the current state of what the RT patches are like in
Ubuntu.

Can someone confirm that they can start X alright please?
