own driver crashes + patch

Hi all, 

I'm writing a Framebuffer driver for an embedded system that contains an
LCD display and and Toshiba T6963 controller. 

I had the problem, that my driver crashed because the screensize
(126x64) is lower than the boot-logo (80x80). And this parameter is not
checked in fbcon.c

To see a Kernel with the virtual framebuffer crash, apply the patch
vfb.diff and enable the Virtual Framebuffer in your configuration and
kernel command line.

The workaround is shown in file fbcon-2.4.18.patch. 
I'm not sure if that is the right place to check the boot-logo size.
Perhaps somebody has a better idea.

Best regards 
Yves Jaeger
