This is a known problem and there is a patch for that:

http://bugs.centos.org/view.php?id=3156

Your kernel is so old (meaning many security holes). Please update the
system and while doing so, grab the centosplus kernel which has the
fix for this issue.

# yum update

should install the latest centos5 kernel (centosplus if you installed
your reiser supporting kernel from there) and that should have the fixes
installed.

How about reading the bug you linked where it states quite explicitly
that it was fixed in the 5.3 centos plus kernel
(2.6.18-128.el5.centos.plus) and recognising the version number as
previous to the one you just installed...

And if you wish to confirm that the patch is in the current centosplus
kernel you are running, issue a command:

rpm -q --changelog kernel-`uname -r` | more

You will find this line:

- added reiserfs patch (bug3156)

somewhere near the top of the output.
