Re: Frame buffer Device Missing
I don't know if this fits well in the LI`P' list.

Frame-buffer modes are sorta slow unaccelerated modes. i810 should work
(its supported right?). FB uses VESA BIOS which is standard and
independent (to an extent) of the graphics chip.

The device driver need be in the memory for the device to work. Did the
system boot up with Frame buffer console driver ? (Saw li'l tux picture?).
Try setting lower modes ? (0x301, 0x303 ...). Remember you ought to have
framebuffer support enabled while compiling the kernel.
[Oops. I forgot about your previous post.]

Which `X'. change the /etc/X11/X.
Select a single Display sub-section in the screen section using the
DefaultColorDepth parameter of `screen' section. In that `display'
section place the resolution of the frame-buffer in the beginning.
You are using 791 (0x317) = 1024x768 16bit
Modes "1024x768" ..
Frame buffer device resolution cannot be changed once the linux boots
up, I think it is due to this that X does not startup. X seem to look
for the first mode specified in the apropriate color depth `Display'
