Tiancheng,

  I got it to work.  It had to do with my kernel boot command line in grub.conf.  I had to add:
 vga=0x318 video=rivafb
  I used the standard kernel that came with Core 4 and all is well.  Like magic the /dev/fb and /dev/fb0
were defined by the system (??).  There is still a lot I don't understand but it is a start.  Now I need to
know how to make more Frame Buffer devices!

  Thanks for your time.

ps. The HOWTO.html was not any help for my NVidia video card problem.  I found it by googling
around for a time.  Bits and pieces!

I wonder your kernel is not configured properly. go to http://www.faqs.org/docs/Linux-HOWTO/Framebuffer-HOWTO.html for more details.
 
As for the disapearing of node, put "mknod /dev/fb0 c 29 0" in your booting up sript will create the node when boots up.
Good luck!

Tiancheng,

  My typo!

$ sudo mknod /dev/fb0 c 29 0
$ cd /src/FB
$ sudo ./a.out
Error: cannot open framebuffer device /dev/fb0. - No such device rc=-1
$ ls -lrt /dev/fb*
crw-r--r--  1 root root 29, 0 Aug 18 12:21 /dev/fb0
$

  Also, the nod disappears after a boot.
