Is the swap partition large enouth for the kernel to dump core ?
If so try sysctl -w ddb.onpanic=0

If this isn't possible, you can try to get the keyboard code from X and
run this in a simple program (which won't turn the screen to graphic mode).
My guess is that it panics when trying to open the keyboard device, or
do some ioctl to initialise it.
