The Lenovo W500 laptop hangs inside an SMI on brightness changes,
I thought it just needed the VGA disable but it turned out to require
slightly more work, setting the MC locations up just like the IGP
chip requirements seems to make it all happy again and I can boot
and play with brightness.
We should probably just do this for all chips and give up the VRAM

Immediate readback seems faulty on some chips. I
suspect it takes a while to get through the fifo
to the actual register backbone. There's no need
to read it back, so, just write the driver's copy
of the register's value directly.

When we are evicting from VRAM->RAM we allocate the ttm object,
but we don't set the caching policy on it before blitting into it.
This means on AGP we end up blitting into cached pages, and
the CPU later flushes out on top of them. This was mostly seen as
font corruption.
The other question is why we don't evict VRAM->GTT in a lot of cases,
this would save us some cache transitions since a lot of objects
that are evicted from VRAM will probably end up being pulled back in
a few operations later, and evicting them to system memory involves
2 unnecessary cache transitions.

In commit c1c7af6089 ("drm/i915: force
mode set at lid open time") the intel graphics driver was taught to
restore the LVDS mode on lid open.
That caused problems with interaction with the suspend/resume code,
which commonly runs at the same time (suspend is often caused by the lid
close event, while lid open is commonly a resume event), which was
worked around with in commit 06891e27a9
("drm/i915: fix suspend/resume breakage in lid notifier").
However, in the meantime the lid event code had also grown a user event
notifier (commit 06324194eee97a51b5f172270df49ec39192d6cc: "drm/i915:
generate a KMS uevent at lid open/close time"), and now _that_ causes
problems with suspend/resume and some versions of Xorg reacting to those
uevents by setting the mode.
So this effectively reverts that commit 06324194ee, and makes the lid
open protection logic against suspend/resume more explicit. This fixes
at least one laptop. See
http://bugzilla.kernel.org/show_bug.cgi?id=14484
for more details.

Limiting the pll output range is a good thing generally as
it limits the number of possible pll combinations for a given
frequency presumably to the ones that work best on each card.
That's why the limits are in the bios tables. However, certain
duallink DVI monitors seem to like pll combinations that would
be limited by this at least on pre-DCE 3.0 r6xx hardware. This
might need to be adjusted per family or per clock range in the
future.

The problem boils down to the order when the bit11
of the texture size is or'ed to the original width.
In the end each mipmap level has the same width or
height because of that 11 bit is ored to the scaled
down lod with and thus blows up the size again to the
full size or more due to the power of two rounding
afterwards.
The attached patch changes this order so that the
texture sizes are computed correct. Also the on error
the yet missing inputs to the size computation are
printed which helped me to find out where it really breaks.
