Frame buffer Device Missing

[vnair@xxxxxxxxxxx]

Hello List,

While configuring X on linux (Redhat 6.2), Firstly i am unable to do it in frame
buffer mode. The Video card is Intel810 (PIII).

While configuring it to be in frame buffer mode, it gives an error

     open_framebuffer: failed to open /dev/fb0 (No such device)

Although the /dev directory contains all of them :

[root@telspec-p5 X11]# ls -l /dev/fb*
lrwxrwxrwx    1 root     root            3 Nov 15 00:26 /dev/fb -> fb0
crw-r--r--    1 root     root      29,   0 Nov 24 10:21 /dev/fb0
lrwxrwxrwx    1 root     root            8 Nov 23 17:26 /dev/fb0current ->
/dev/fb0

crw-------    1 root     root      29,  96 Nov 24 10:00 /dev/fb3
crw-------    1 root     root      29, 128 Nov 24 10:00 /dev/fb4
crw-------    1 root     root      29, 160 Nov 24 10:00 /dev/fb5
crw-------    1 root     root      29, 192 Nov 24 10:00 /dev/fb6
crw-------    1 root     root      29, 224 Nov 24 10:00 /dev/fb7

I have done following steps:
1. added a line vga=791 in /etc/lilo.conf, and executed lilo -v command and
rebooted the system
2. At LILO boot prompt i start it with option "linux 3 vga=791"
3. In XF86Config file, added another entry just under Screen section containing
the section for svga mode
4. Made a link for X "ln -s /usr/X11R6/bin/XF86_FBDev X"

Now while running X it give the problem. What can be the cause ?

TIA
