OK, here's what the ocfs2 team told me:

The patch in Linux is a safety check for handling the case
where the heartbeat is on the same disk as the filesystem
data.  If this is the case (and I think this is always true
for OSR), you must either use the mount.ocfs2 command
to do the mount (which does the right thing and notifies
the kernel about it) or must specify "-o heartbeat=local" if
you use the mount command.

So since I am using an upstream Linux (2.6.29), I had to
workaround this by hacking an ocfs2 kernel source file.
