Latest i810 driver

[Lukas Hejtmanek]

Hello,

just tried:
current:xserver, app, lib, proto, drm, mesa from git (default branch)
current:xf86-video-intel - modesetting branch.

Observations:
EXA - no more image corruption, good. On the other hand, x11perf -shmput500 
      is about FIVE times slower than XAA.

RANDR - if an application changes resolution and crashes, xrandr -s 0 results in
	screen corruption. xrandr -s 1 && xrandr -s 0 fixes the corruption.

CLONE - works (If I specify MonitorLayout "CRT,LFP") good. It even work as
	I would expect - setting the LFP (LVDS) to 1280x800 and the CRT to
	1280x1024. However, in this mode, if I do xrandr -s 1, the LVDS goes
	blank and screen is only at the CRT (-s 1 corresponds to 1152x870), OK
	LVDS is not capable to use this mode. If I do xrandr -s 2 (corresponds
	to mode 1024x768), the LVDS is still blank and CRT has the mode,
	I guess this is wrong. At this point, I was unable to restore screen
	on LVDS (except returning to the text mode).

DRI - terrible slow (ppracer is unplayable at all), using INTEL_BATCH=1 does
      not help. (glxinfo:
		      name of display: :0.0
		      libGL warning: 3D driver claims to not support visual 0x73
		      display: :0  screen: 0
		      direct rendering: Yes)

Xserver startup - LVDS is two times turned off and on. After first turning on,
		  garbage on screen is displayed, after second turning on,
		  correct X screen is displayed.

Hope, Eric or Keith find this feed back useful.
