[SYNC] synced with 2.4.5

[James S. <jsi...@tr...>]

Hi!

  This might be a improvement as several people had trouble with 2.4.4. Also 
the console display drivers initialization code has been cleaned up alot.
It is really easy now to create a display driver. Also you can now have
mda if configured by itself boot up right away like vgacon instead of
later. I use this with fbcon to debug fbcon. Also we no longer need dummycon
right away if every. Since the log buffer for printk is seperate I have it
so printk messages are buffered until a console driver is loaded. Then it
is flushed to the screen. This was a big step. The next steps for me is in
order of most to least important are:

1) Write the font drawing code for dummy framebuffers. Important for
   vesafb and sa1100fb.
 
2) intergrate Andrew Morton's console/printk sync patches.

3) Fix VC resizing. You will be able to use stty to change your resolution
   :-)

4) Cleanup font handling.

5) Redo all the unicode code and have it work with Unicode 3.0 standard.
   It really sucks right now.

6) Rewrite GPM and remove selection code in the kernel. It doesn't belong
   their IMHO. 

6) More improvements in the VT emulation code.
