No, just any console, like VGA console, a framebuffer driver (like l4fb)
or a serial console (like l4ser). There's no difference from normal
Linux. If you do not have a console some way you won't see anything.

No, that just means that l4io should not acquire all interrupts and
relay them via the omega0 interface. It's fine this way.

Well, must be something else. This option shouldn't have any influence
on the issues.
