Lyude Paul ff459c2dc0 video/console/vgacon: Print big fat warning with nomodeset
It's been a pretty good while since kernel modesetting was introduced.
It has almost entirely replaced previous solutions which required
userspace modesetting, and I can't even recall any drivers off the top
of my head for modern day hardware that don't only support one or the
other. Even nvidia's ugly blob does not require the use of nomodeset,
and only requires that nouveau be blacklisted.

Effectively, the only thing nomodeset does in the year 2018 is disable
your graphics drivers. Since VESA is a thing, this will give many users
the false impression that they've actually fixed an issue they were
having with their machine simply because the laptop will boot up to a
degraded GUI. This of course, is never actually the case.

Things get even worse when you consider that there's still an enormous
amount of tutorials users find on the internet that still suggest adding
nomodeset, along with various users who have been around long enough to
still suggest it.

There really isn't any legitimate reason I can see for this to be an
option that's used by anyone else other then developers, or properly
informed users. So, let's end the confusion and start printing warnings
whenever it's enabled.
