Yes, after some thinking I figured that a software that I put in the initramfs could possibly drive the display even without much kernel support. With a working in-kernel driver I could get something displayed a bit earlier still. More importantly there is the question of displaying something useful on the display. With an in-kernel driver it should not be overly difficult to add support for echoing what goes to the console on the display as well. With a separate software I have no idea how to collect some reasonably useful information. I mean, if the machine is running correctly I can easily ssh in and run full suite of analytic tools and fill my monitor with various useless information about the system. It's the case when something does not seem to work when the display would come handy.
