The frame buffer driver for your graphic card is not in the
kernel or could not bee initialized properly, so this is one
reason for missing /dev/fb0.

Are kernel modules installed in your system? What is the output
of the command below?

ls -l /lib/modules/`uname -r`/kernel/drivers/video


If you do not know which graphic chip is in your system,
you might want to run

lspci -v | grep VGA

Then you have to install the appropriate frame buffer driver
kernel module or alternatively to build the kernel with frame
buffer driver included.
