If you can't avoid doing a set_par duing initialization, you can always memset
the fb memory to the background color.  Not sure if it's going to completely
remove the garbage as vgacon continues to write to vga memory far beyond
fbdev registration.

Note: Doing a set_par during initialization will produce an unusable display 
if you load the driver without fbcon. You can always restore by loading
fbcon or running con2fbmap.
