I know this patch doesn't change the current behaviour, but a common
function console_get_by_name() should return return the console by name
regardless of whether it's active or not.
For the loadx code this would be a net win aswell. I think this code
should not depend on an active console but the other way round: It
should clear the CONSOLE_STDIN/CONSOLE_STDOUT during loadx operation.
This way we could easily make sure there are no printf message garbling
the line during transfers and still we could have console messages on
other consoles.
