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!
