ive translated the bug report from the spanish

what he says is: when I use applications that require a frame buffer I am denied
access to /dev/fb0 I use devfs, what can i do? ive installed the gentoo livecd.
 
there's nothing in the /dev/fb/ directory and ive selected the use frambebuffer
kernel option, i dont know if this helps, but i have a GForce 2 MX 400.
saberlo

thanks in advance and sorry for asking in spanish

OK... Here is the small dirty howto for fb... 
Follow the steps and if it'll work for you... :-))

1. Compile kernel
a) Console drivers
 [*] VGA text console
 [*] Video mode selection support
 < > MDA text console (dual-headed) (EXPERIMENTAL)

b) Console drivers -> Frame-buffer support
 [*] Support for frame buffer devices (EXPERIMENTAL)
 [*] VESA VGA graphics console
 Everything else is SWITCHED OFF for now

c) make dep && make clean bzImage
d) mount /dev/hda1 /boot
e) cp arch/i386/boot/bzImage /boot

2. Switch on the framebuffer at boot
 easiest way is from grub
/boot/grub/grub.conf have a kernel line like this:

kernel /boot/bzImage root=/dev/hda3 vga=790

that vga=790 will switch up the framebuffer device
# VESA framebuffer console @ 1024x768x32k


3. reboot

If all is ok, you will see the TUX at the boot
and there will be /dev/fb0 and /dev/fb/0 

hope this helps...

roman proposed a solution for this bug which apparently does the trick ... the user who reported it hasn't complained again ... so i closing this bug.
