Got it!
The value of "KERNEL_LOGLEVEL" in /etc/sysconfig/syslog was set to 1 (the
default value). Setting this to 7 solved the problem.
This can be done either by manually editing the file (and running
SuSEconfig afterwards) or using YAST2 -> system -> editor for
/etc/sysconfig files -> System -> Logging -> KERNEL_LOGLEVEL.
Now my console is pretty chatty...
Thanks!

Suse set the kernel log level when starting the klogd daemon. I would
prefer that klogd not modify the log log level. If a change is to be
made to the default log level, why not make the change in sysctl.conf?
adding KERNEL_LOGLEVEL = "7" to /etc/sysctl.conf does not work for me
(openSuSE 10.2) - this line seems to be simply ignored. The value
in /etc/sysconfig/syslog gets used, and if it's commented out the default
value of 1 is used.
A value of "5" turned out to be "chatty enough" for the sysctl message bodies.
Why do you think setting KERNEL_LOGLEVEL in /etc/sysconfig/syslog is evil?
I think tuning the system is the purpose of /etc/sysconfig/* files?

You are correct in that setting a value in sysctl.conf is changed by the
klogd parameter. The purpose of klogd is to extract kernel messages from
the kernel buffer and pass them to the syslog-ng daemon. It is not its
purpose to tune kernel parameters. The purpose of the sysctl command,
and sysctl.conf at boot time, is to tune the writable parameters shown
in /proc/sys. While many people use the echo command, you can modify the
kernel log level at any time with the command sysctl -w kernel.printk=8.
The log levels are 0 through 7, and the specified log level says print
all message that are less than this value. This is different than syslog
configuration, where the log level specifies values that are equal to or
less than.
Another reason for using sysctl.conf is that you control the log level
earlier in the boot process. This may be important if you are looking
for debug messages, which are log level 7.
