howto log screen output while booting

[Johan Scheepers <johansche@telkomsa.net>]

Good day,

On wheezy testing how can the screen output be logged.

There seem to to be a bit problem with some missing modules.
Too fast can not read it.

The OS is running fine.
I am actually impressed. My samsung scx-4624f was installed in seconds 
after switch on and connected to PC. On other OS,ses and even debian 
squeeze it took some doing.

Thanks
