Hmm... this is just a pointer. At least you'll know what /dev/fb0 is for.

http://tldp.org/HOWTO/Framebuffer-HOWTO-3.html

"A framebuffer device is an abstraction for the graphic hardware. It
represents the frame buffer of some video hardware, and allows
application software to access the graphic hardware through a
well-defined interface, so that the software doesn't need to know
anything about the low-level interface stuff [Taken from Geert
Uytterhoeven's framebuffer.txt in the linux kernel sources]"

http://tldp.org/HOWTO/Framebuffer-HOWTO-5.html

"You'll need to create the framebuffer device in /dev. You need one
per framebuffer device, so all you need to do is to type in mknod
/dev/fb0 c 29 0 for the first one. Subsequent ones would be in
multiples of 32, so for example to create /dev/fb1, you would need to
type in mknod /dev/fb1 c 29 32, and so on up to the eighth framebuffer
device (mknod /dev/fb7 c 29 224)"

Just to check the MAJOR and MINOR numbers (also do "man mknod")
http://lkml.indiana.edu/hypermail/linux/kernel/9807.3/0929.html

It looks like the preupgrade process needs some polishing.

HTH,
