Ah, that tux logo.  Yes that one gets displayed if you compiled in
framebuffer support to your kernel.  It is defined in
include/linux/linux_logo.h, so you could change it to an invisible image.
(Or hunt through the kernel code for the bit that enables it, and get
rid).

That still leaves the flashing cursor though.
