So netconsole is a write-only kernel console.  Kernel messages will go
out, but your init process, etc will not.  For syslog type things, you
may want to look into a syslogd that does network.  I don't know how
netconsole support in u-boot works, but it sounds like it's a network
aware application that you can telnet into, rather than Linux's
netconsole.
