Exactly. I'm also testing older distros quite regularly with new kernels
and there's it's useful to have an impression of a kernel's output at a
glance. Adding _any_ userspace change (even if i wanted to do it, which
i dont) is out of question. So these are distinct, well-defined usecases
that nobody has brought any coherent argument against yet. VGA isnt
going away anytime soon, certainly not on my testboxes.
