Have you decided which alternative ? If I remeber correctly this was discussed
on security-audit list.

Yes, the fixed version is 1.4.1 (not 1.4 like I remembered)
I noticed the problem about 2 months ago with my laptop, because after every
suspend/resume (reloading the network driver) klogd ate 100% cpu. After
searching if others had noticed the same symptoms I found that 1.4.1 has the
bug fixed.
The 1.4.1 version is available from:
http://www.ibiblio.org/pub/Linux/system/daemons/
(I think the klogd cpu bug is mentioned in the changelog).
