I changed the screen size from 1024x768 to 800x600 with a gcc4 build from
r35261 in qemu and I got the following SegFault:[[BR]]
{{{
vm_soft_fault: va 0x0 not covered by area in address space
vm_page_fault: vm_soft_fault returned error 'Bad address' on fault at 0x8,
ip 0x80046e7d, write 0, user 0, thread 0x178
PANIC: vm_page_fault: unhandled page fault in kernel space at 0x8, ip
