The origin check for bring back max value for '0'
backlight level is ok for legacy or combo control method
as '0' mostly doesn't act in ideal lowest level. But it
breaks in using kernel control method which should provide
a reasonable backlight range.
This is tested fine on T61 with thinkpad_acpi module.
We can get a case with gnome-terminal + links, where we get two arrays
of glyphs all with 0 width and 0 heights in them. If this happens
we manage to get to this case without any buffer setup and segfault.

This results in allocation overhead for small (8x8-128x128 or so) pixmaps with
DRI2, but we're interested in looking at tiling them in general in the near
future, anyway.
The call into intel_batch_flush() will invalidate the pI830->batch_bo
stored in bo_table[0]. Fix it by re-read the refreshed value.

HDMI is compatible with DVI, and we've seen many boards that
use HDMI port for DVI output.
So Zhenyu proposed this flag: i830_hdmi_priv.has_hdmi_sink
to indicate the presence of HDMI capable monitors.

The GM45 b-spec requires the use of the longer hotplug activation period,
but does not require looping twice over the detection logic. With this
patch, CRT detection appears solid on my GM45.

Color knobs was set with higher modifier which caused strong color
on TV screen. Setting fixed point modifier to default 1.0 makes picture
on TV look nicer.
This required reordering the relocation emits for surface/binding table
so that we didn't add new relocations to things that had already been
relocated at (the check_aperture requirement).
This was an early attempt to support display switch hotkey. It never really
worked, as the events didn't show up when they should. It also cost a wakeup
every second to check just in case, instead of taking an interrupt like we can
now using ACPI. Additionally, some machines apparently get stuck with the
event set and end up DDCing checking for new devices every second and
smashing your video modes.
