I am not sure about dmesg, but Sid has this in /etc/sysctl.conf:

# Uncomment the following to stop low-level messages on console
# kernel.printk = 4 4 1 7

I would therefore assume that this adjustment of the kernel's printk
parameter is the "recommended" way of stopping the messages on the
console. If you want to change the setting with immediate effect you can
use

echo "4 4 1 7" > /proc/sys/kernel/printk

Uncommenting the line in /etc/sysctl.conf makes this permanent over
reboots. (I believe that you have to add this line yourself on Sarge.)
