I had the same problems (X doesn't start unless i915.modeset=1 & system crash when playing a video with VLC) with a Samsung X05 and an Acer Travelmate 4001LMi.

The first problem was solved this way (in both computers):

 - start with Live CD and i915.modeset=1, install the system, not reset at the end and do:

   - Menu System > Administration > Disk Utility, mount the disk in which we have installed the system,

   $ cd /media/<tab>/etc/default
   $ sudo cp grub grub.bak
   $ sudo pico grub

   - GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.modeset=1"

   $ cd /media/<tab>/boot/grub
   $ sudo cp grub.cfg grub.cfg.bak
   $ sudo pico grub.cfg

   - look for 'quiet splash' and add "i915.modeset=1" at the end (without quotes).

 - reset without CD,
 - update system,
 - update grub:

   $ sudo update-grub

 - reset & done!

The second problem was fixed by upgrading the kernel like explained in:

 - https://wiki.ubuntu.com/X/Bugs/Lucidi8xxFreezes

Another problem with the Acer Travelmate is that it doesn't shut down completely, which is an issue related with another bug.

Hope this could help someone.
