That experimental kernel (2.6.34-rc3-51.1~karmic) didn't do it for me: my
i855 froze up during login. I was running it with the following packages:
   libdrm 1:2.4.11-2+karmic3
   mesa 1:7.4.1ubuntu6+karmic
   xserver-xorg-video-intel 2:2.9.0-1ubuntu2.2~gomyhr1~clipsolids~karmic
My GPU: Intel 82852/855GM [8086:3582] (rev 02)

Maybe a different set of packages would've worked better with that kernel?

So far the only stable combination I've found is Geir Ove Myhr's (Jan. 2,
2010)
linux-image-2.6.31.1-855gmtest599-git522bb74_gomyhr1_i386 (downloaded from
http://www.kvante.info/855GMfreeze/) running with the standard Karmic
packages:
   libdrm 2.4.14-1ubuntu1
   mesa  7.6.0-1ubuntu4
   xserver-xorg-video-intel 2:2.9.0-1ubuntu2.1
