Except for the sole "quiet" flag, I have this in my kernel tree:

It allows one to finely specify how much noise or silence the user wants.
conlevel=4 makes it quite silent (still shows some minor erros [1]), and
decreasing that of course will make it even more silent.
[1]
sda: asking for cache data failed
sda: assuming drive cache: write through
piix4_smbus 0000:00:07.3: Host SMBus controller not enabled!
These three are then gone for me with conlevel=3. dmesg still
records all messages (a good thing(tm)).
