Yes, this is possible.  A while back I did this as an exercise of
a video card.  There are several ways to do this, kernel, userland, etc,
but probably easiest is to load a bitmap in the kernel.

If you feel like going one step further, you can do what I did and add
alpha blending for the text console over your image.  Doing
graphics-on-graphics alpha blending is quite expensive so it is probably a
good idea to expose this feature of your video card, however getting the
documentation for your particular card will be a chore.

This ofcourse is just a for-fun thing, and one would never expect such a
feature in the kernel.  A properly designed userland app would best fit
this.
