Suppress all boot output (framebuffer?) - embedded linux distro

[voidexp@gmail.com (Ivan Nikolaev)]

Hi everybody! I'm new to linux kernel development (very very little 
experience), time ago have began studying Operating Systems, even 
written a simple x86 2-stage bootloader for my supa-dupa-noob-os (which 
never ended up in something working). Anyway, that was just to explain 
what kind of a noob you talk to. ;)

I'm developing an ubuntu 12.04 (LTS) based embedded distribution, which 
basically is a normal ubuntu stripped down to bare minimal packages, 
which runs a minimal XOrg server with one single full-screen 
application. What I want is to suppress every single char of console 
output since the bootloader passed control to the kernel, and possibly 
show instead of that some static text and/or image. What I thought is to 
try to disable printk-s and to write some kind of patch which uses the 
framebuffer to show the logo. Is that possible/difficult? Can you 
eventually explain where I should dig?

Thanks in advice!
