Lots of people use this. First make GPM use /dev/vcs* and then think
of removing this feature. I.e., not for 2.2.

No, lots of people use the unicode stuff as it's the only sane way to using
non-ISO-8859-1 charsets and still being able to draw VT100/IBM graphics.

I think it should be just ifdef'd out.

They are used when debugging parts of the kernel. Maybe make them optional,
but certainly don't remove them.

Have a nice fortnight
