That was a good tip.  Using the default dmesg setting and entering <0>
-> <3> into the message string it logged across the network, <4> and up
it did not.  So netconsole seems to be working as expected.  The mapping
of numbers to types (error, emerg, etc.) seems not to be in the man
files, or at least I have not found it there, but is in:

/usr/include/sys/syslog.h and is


#define LOG_EMERG       0       /* system is unusable */
#define LOG_ALERT       1       /* action must be taken immediately */
#define LOG_CRIT        2       /* critical conditions */
#define LOG_ERR         3       /* error conditions */
#define LOG_WARNING     4       /* warning conditions */
#define LOG_NOTICE      5       /* normal but significant condition */
#define LOG_INFO        6       /* informational */
#define LOG_DEBUG       7       /* debug-level messages */
