Try 

dmesg -n 8

to raise the logging level and try

echo '<7>David Test' > /dev/kmsg

That should produce output:

Jan 27 08:32:24 10.10.12.43 [3098843.050122] David Test

The 7 is the logging "severity", try that with <0> and you should send a 
message to anyone on the system.

Does this help?

cheers

Carsten
