nanogui: Thread: Framebuffer support

Hi all,

        I have 'Fedora Core 3' installed in my machine and Video card in
my machine is 'S3 ProSavage KM133'. Now I want to work with
framebuffer. If I run 'fbset', it says :

[root@aveek ~]# fbset
open /dev/fb0: No such file or directory
[root@aveek ~]#

I have checked in '/dev' that there is no special file called
'/dev/fb0'. So most probably kernel has no support for framebuffer.
To do that I need to recompile the kernel. Well, but I don't know
what to set in the in 'xconfig' for my Video Card 'S3 ProSavage KM133'. 
        Can anyone tell me this and what to do next in order to
directly access framebuffer ?

Thanking you all,
Regards,
Aveek

Setting up linux fb is sometimes a pain.  You should google for
this and see what other sites say about kernel setup.  And yes,
you'll need to create /dev/fb0 yourself.  If you've got a newer
card, you can sometimes run basic VESA bios support, 
rather than the sometimes painful process of getting the video
card driver selected.

FC3, hope you are aware that you must pass additional arguments to the
kernel to make it boot into Framebuffer mode. This must be done in the
/etc/grub.conf file.

I have pasted some parts of my gub.conf here, (FC4) . The second block
is basically just a copty of the first block, but notice the VGA=0x305 added
to it.
Thats what tells the kernel to boot into framebuffer mode.

title Fedora Core (2.6.11-1.1369_FC4)
        root (hd0,0)
        kernel /boot/vmlinuz-2.6.11-1.1369_FC4 ro root=LABEL=/ rhgb quiet
        initrd /boot/initrd-2.6.11-1.1369_FC4.img


title Fedora Core (2.6.11-1.1369_FC4) With Framebuffer
        root (hd0,0)
        kernel /boot/vmlinuz-2.6.11-1.1369_FC4 ro root=LABEL=/ rhgb
vga=0x305
        initrd /boot/initrd-2.6.11-1.1369_FC4.img
