Now it is, provided you can make your kernel boot completely without text 
output. The only kernel nbi I have here insists on putting a string like 
"Uncompressing kernel..." on the screen and complaining about my pci 
subsystem although I supplied "quiet" as command line option. No matter, if 
you can have a silent boot, an image can be displayed which will last until 
the first process writes to console.

I just used ansiesc, which is inside etherboot.
You can download the .diff file and an example ansi graphics file from
  http://feldhausnetz.de/splash.tar.gz
Then enable option -DSILENTFORSPLASH
and put an ansi graphics file so that tftp can reach it as /splash.ans
In that tar gz file, there is an example. If you want to disable it, just put 
a zero-size file to the same location as splash.ans (e.g. "rm splash.ans; 
touch splash.ans") or disable the -DSILENTFORSPLASH option in your config 
file.
Please tell me if it really works, as I said before, I cannot make my kernel 
really shut up.
BTW: I implemented this starting from a bare etherboot 5.0.6.
BTW2: Image size is still too much. This should become much better with a 
multicast downloading option. In development.


Documentation:
-DSILENTFORSPLASH
This option disables any etherboot-side output beginning at the moment the 
kernel download is started. Instead, it loads the file '/splash.ans' (from 
the same location it would load a kernel '/vmlinuz') and displays its 
contents. This option requires -DANSIESC and -DGFX to work properly.
