Attached is a patch against linux-2.5.50 + your fbdev.diff.

Applied :-)

b.  Another rewrite of fbcon_show_logo() so it's more understandable
(hopefully).  I also added support for the rest of the visuals, but
untested yet.
Not tested:
static psuedocolor, mono01, and mono10.

I have a mono hga card.

c.  prevent fbcon module from loading if no fbdev is registered.  Also
made fbcon module unsafe to unload (for now).  This is optional, of course.

It is a good idea until we have the ability to switch back to text mode.
