When I try to use this line of options I get an error message saying
i915_enable_fcb is an unknown parameter. Is that for kernel 3.2 only?

What does that parameter refer to? I tried googling on "i915_enable_fcb"
to no avail.

For my Lenovo T520 using only the integrated Intel graphics, do I need
drivers other than xserver-xorg-core, xserver-xorg-video-fbdev, and
xserver-xorg-video-intel?

The reason I ask is that I sometimes, when experimenting with different
configurations get errors suggesting that I need the vesa driver, and
wonder if that is related to the error I get concerning the
i915_enable_fcb?

I don't run games or any video intensive apps. I am currently running
3.0.0-1-amd64.
