And Intel typically needs i915kms.ko, supplied by the OS.

Regarding nVidia, there are, if I remember correctly,
three ports that can be used as the X driver: First,
the proprietary driver with the best results (nvidia-driver,
can be accompanied by nvidia-settings and nvidia-xconfig
if needed), the open source driver with limited support
(nouveau), and the "nv" driver that comes with X (if I
remember correctly) that doesn't have any 3D capabilities.
If you are not using any of them, VESA (X's built-in
fallback "driver") will probably still work.

No idea about AMD / ATi, I'm no longer using one since
the support went from "everything works" to "basic graphics
with 1 fps and we don't care"...
