One more patch for Alpha console issues...

I have been working with someone who has a DS10 and graphical console.
The set of patches I had done so far slowly made it go farther before
dying due to kernel stack issues but it was still not booting all the
way.  AFAIK everyone else who has been testing things had serial consoles.

He reports this patch does fix his machine to the point it boots.  I'll
go ahead with this in a day or two if nobody has any further comments.
I know at least Bruce seemed interested in this, saying that these moves
shouldn't *really* be needed and that it would be nice to find out a
bit more about what is really the root cause of the problems.

This patch leaves the promcons initial console in place until the same
point I had found the call to make_dev() needed to be moved.  It then
calls the system-specific console init routines that (may...) swap
the console to be a different driver.  This had not been needed on the
machines with serial consoles but it apparently is for machines with
graphical consoles.

Any further thoughts?  Thanks...
