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

IIRC, isn't that what ubuntu 12.04 does during boot stage by default ? i mean, no boot message shown....
