Hi,
  Here's a fix - it's a missing NULL check in get_framebuffer_info

(I think this is an Ubuntu specific issue - I can't see the code in the mainline.
I think it was triggered by the code in  
http://old.nabble.com/-PATCH-0-2---Maverick--boot-frambuffer-crash-fixes-td29297713.html )

lshw goes and creates it's own fb devices in tmp to prod them, and
creates minor 1 and tries to open it and BANG.
