Mini2451 disable cursor during boot

bluscape
I'm booting a custom logo on the Mini2451 with a TD35 display and must
disable the cursor on the frame buffer to get rid of the black square and
cursor in the corner.

I disabled this on the Mini2440 by passing the kernel command line
parameter vt.global_cursor_default=0 but this does not work with the
Mini2451 kernel. All I get is a white screen. Not passing this parameter my
boot logo displays fine but with a black square in the corner.

I've tried various things but just don't succeed. I've tried the kernel
command line parameter. I've tried some things in vt.c and fbcon.c but no
success. I've also tried the kernel command line parameter cur_default=1.

I'm using the Superboot2451, FriendlyARM linux-3.6-20140106 and a custom
busybox file system.

I'd appreciate your help and ideas.
