X freeze with Intel I946

Installed Arch 64 on box with Intel I946GZ onboard graphics

lspci

00:00.0 Host bridge: Intel Corporation 82946GZ/PL/GL Memory Controller Hub (rev 02)
00:01.0 PCI bridge: Intel Corporation 82946GZ/PL/GL PCI Express Root Port (rev 02)
00:02.0 VGA compatible controller: Intel Corporation 82946GZ/GL Integrated Graphics Controller (rev 02)
....

kernel26 2.6.37.5-1
xorg-server 1.9.4.901-1
xf86-video-intel 2.14.0-3

Run kdm (login as root and /erc/rc.d/kdm start) :

kdm's background appears distorted [*1 below]. sometimes with mouse cursor and it's moving, sometimes without cursor. Except that the screen is frozen. Xorg.0.log is [*2 below]

When the display freezes it won't change anymore, but the computer "behind" is still responging. If i Alt Ctl F1 (to the vt where root is logged in) and run commands, PC responds :

ls -R / --> hard drive activity

killall X --> screen goes blank (and remains like that no matter what i do, even if i restart X) and the computer is stell responsive "behind" the blank screen

init 6 --> reboot after few seconds

ONCE EVER in one of the times when kdm mouse was movable I tab'd into the user password text fields (they appeared as soon as I began typing in them), logged in successfully, used the desktop for less then a minute and it froze dead. I tried to reproduce that and could not. Xorg.0.log from this time is [*3 below]

If i disable KMS (add nomodeset in grub) computer works ok except minor issues (sometimes cursor disappears in text fields etc) and limited resolution (up to 720x400 in vt's and 1280x1024 in X)

Without KMS, KDE's desktop effects are very slow (and full of unpainted areas) with opengl, and work perfectly with xrender

I tried to install Arch i686 in dual boot :

With KMS - same as 64 except the computer is not responding to (Alt Ctl F1 and typing commands as root etc)

Without KMS - same as 64

How to make it work ?
