I have mostly the same problems than other people. I have an Inspiron
510M with an ICH4/855GM chipset (from 2005).

With Jaunty I used the "i195.modeset=0" to fix the X hard crash while
closing lid (which happened whatever action was configured on LID
closed, and could be repeated without any X or acpid running).

While upgrading to Karmic, the "i195.modeset=0" was kept in GRUB
settings and X totally crashed the system at startup: no VT switching,
no sysrq to the rescue. I changed the kernel setting to "i915.modeset=1"
then X started properly and seems to run fine, except for immediate
hardlock as soon as XV is used. This running Karmic's 2.6.32-22.33
(-generic on a Pentium M).

I have asked at least gstreamer not to use XV (eg:
http://www.thinkwiki.org/wiki/Intel_Graphics_Media_Accelerator_950#Issues).

I can try other kernels or settings to help narrow down that XV crash if
that helps.
