Well, the fact is that xserver-xorg-video-intel is not like an
all-in-one driver, it depends on lots of stuff from other packages like
mesa, libdrm, the kernel, etc. With KMS this is even moreso true.

This is why I found downgrading to 2.8.0 to be intriguing. But the
further testing suggests it was just tweaking the conditions. Like I
mentioned this bug is very sensitive to conditions, so it's not
unexpected that you could have a working system, change one thing,
change it back to how it was (as far as you know), and no longer have a
working system.
