That sounds good, I guess. The system is booting and when it's done the
disk LEDs go out. But you need some sort of output. In your grub
configuration you have disabled con, i.e. you have the plain VGA output,
right? For that, you also need to have enabled the VGA option in Linux
(CONFIG_VGA_CONSOLE). When you use con, you should enable the
framebuffer driver (CONFIG_L4_FB_DRIVER). When using con you also need
to set the video mode in the grub entry, i.e. just add
vbeset 0x117
to your grub entry you're booting.
