Silencing Boot Messages / missing quiet parameter?

[luke]

Hello

I have been attempting to find a way to keep my laptop from speaking the 
boot messages, on a new Debian Squeeze install.

The screen quickly switches to GDM, so speakup goes on speaking boot 
messages unless you switch back and silence it, or catch it before the 
switch to the gnome console.

I thought I could use the quiet boot parameter as has been done in the 
past.  However, adding it to the line in the modprobe.d file for local 
configurations, does not seem effective.

In addition, it is not listed as a boot parameter in the version of the 
manual which comes with speakup-doc under Debian, which makes me think 
that the parameter has been dropped for some reason when I wasn't paying 
attention.

Is there some other way to do this now, or was it thought to be useless 
functionality?  Or am I just doing it wrong?
