Hi
Hi Bastian,
The powerpc lpar code adds a prefered console at a very early state,
during arch_setup. This runs even before the console setup from the
command line and takes preference.
It runs before the command line parsing, and so /does not/ take
preference. I thought.

/**
 * add_preferred_console - add a device to the list of preferred consoles.
 ...
 * The last preferred console added will be used for kernel messages
 * and stdin/out/err for init. 

The last console will be added by the console= parsing, and so that will
be used. The console we add in the pseries setup is only used if nothing
is specified on the command line.

cheers
