With the sysklogd-1.4-3 package and the kernel-2.4.0-0.99.5 package, klogd seems to take up all of the available idle cpu time. I'm not seeing this with the kernel-2.4.0-0.43.13 and I also don't remember seeing it with the 2.4.0-ac2 kernel I compiled, so it may well be something in the kernel config.
