What OS are you running?    RHEL4 has a line in its rc.sysinit like this:

dmesg -s 131072 > /var/log/dmesg

You can always put something similar in your rc.local.   Can you tell 
from the logs if syslog ever gets started under 2.6?  Or does it reboot 
before then?

For what its worth, I run CentOS 4 (with a 2.6 kernel) on 1425s.
