Yupp :-)

Direct hit.

Works immediatly. Ok, with some little cosmetic problems: Direct after boot
you can see for (less than?) ~1/10 sec the kernel screen in normal 25/80
resolution. After that you see the Pinguin on the top with funny blinking
characters on the bottom, following with the normal boot messages. The
funny characters scrolls out normaly... look like that a random screen
with resolution 25/80 are inserted when the fb are initialized...

Thanks (:o
