Oops; forgot the kernel message; they are here:

The last message is from when I unbinded nouveaufb.  You can see that my 
default console is the VGA one.


As a small update, compiling in fbcon doesn't help anything.  I haven't 
managed to compile in nouveau yet; there's something in the dependency 
chain somewhere that's modularized, and I haven't tracked it down yet.
