That *is* the coloring, i'm talking about.

In the very buggy cases, i think, everything just hang. Otherwise
initramfs stuff can deal with it.

As i'm pretty much in all that text(tty)-mode stuff anyway, maybe after

color schemas (keyword highlighting); keyboard events. Of course it will
work in such IDE cases, only if driver is a module.
