Hm. In vty_init(), we disabled this with "#if 0":

  #ifdef CONFIG_MDA_CONSOLE
         mda_console_init();
  #endif

We should port the mdacon to Ruby, too.
Maybe someone with an old machine with both VGA and MDA,
can help us with testing. I have neither an one, nor an ISA slot..

And Linux supports other architectures beside ix86 and x86-64,
we ask for help from the different arch maintainers, so we can
or they will port the arch-specific parts.

But in this state, we can start the discussion with the kernel
maintainers. Andrew Morton will have a few kind words for us, I think.

I don't know what backwards compatibility we lose with the Ruby
patch. Think about configuring both vgacon and mdacon into the
old kernel. What vtXX will mdacon use? Is there any software that use
it for display-only mode? Will they work on ruby kernel with only
one keyboard, too, unmodified?

And recently Antonio Daplas modified the fbdev/fbcon subsystems,
we must talk to him as well so we don't step on each other's toes.

The X people will be interested, too. Finally they may accept
your PCI isolation patch, preferably in unconditional mode, e.g.
no keyword needed to have separated X servers working together
peacefully.

I think that's all for now. I think we have to get the ruby patch
into the -mm tree, the sooner, the better.
