Take what I say here with a pinch of salt (building the right drivers
with the right settings to work right on the right hardware is, IMNSHO,
a huge amount of black magic :-)


anyway, I seem to recall that USE=i915 or i965 was the old way of doing
things and you needed to know what chipset to build for. Recent code has
merged all of that nonsense so all you have to do is set
VIDEO_CARDS="intel" and emerge can figure out what to build for the
hardware it's running on.

But I could be completely wrong too, so YMMV :-)
