Well, it would be nice to set the default for newly created consoles.

Perhaps you need to make old ioctls 2.4.X compatible and introduce new
ioctl that sets only "this" console?

Do this:

pavel@amd:~$ echo -e '\e[?8c'

Notice cursor changes to block. Switch to another console. Oops, block
cursor, too.

Its not. Its software generated cursor, and it is only drawn, not
properly hidden. Thats why it behaves like that.

Don't let flashing confuse you. Set it to the red block and you'll see
problem better.

What is that? I can not see it in 2.5.X.
