2.6.20: Modular fb and logo crash

If you don't have any builtin frame buffer device driver and insmod a frame
buffer device driver, the logo code will still try to display the logo (which
is __initdata). This may cause a crash.

Originally (2.1.x, is it that long ago I used a modular frame buffer device
driver?), this didn't happen because initmem_freed (which no longer exists) was
checked. BTW, there's still a comment in drivers/video/console/fbcon.c about
this.

Anyone else who's seeing this? Anyone with an idea how to fix this?
Moving the logo code to userspace is not considered a solution ;-)

Thanks!

I used to see this when loading from a booted system, but not when the 
modules were in initrd. Don't know if that offers you any help or not. 
Clearly you want the fb built-in so you see the penguins, anyway. ;-D
