This works if I disable "EARLY_PRINTK". To do that I need to patch Kconfig :

--- a/arch/m68k/Kconfig.debug
+++ b/arch/m68k/Kconfig.debug
@@ -11,7 +11,7 @@ config BOOTPARAM_STRING
        depends on BOOTPARAM

 config EARLY_PRINTK
-       bool "Early printk" if EMBEDDED
+       bool "Early printk"
        depends on MVME16x || MAC
        default y
        help
