I have this issue on my Dell Inspiron 1525 as well. I have a few other graphical issues w/ this Intel card as well. Marcelo above me had a good idea about the screencast. I'm adding mine, and it shows a similar experience.

Here is my lspci:

me@laptop:/var/log$ lspci -vn |grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller [8086:2a02] (rev 0c)

The other issue I have is that when I boot the machine from cold, or restart it, X will NOT load. If flashes a black screen, and then garbage, and then black, and then black. I see the hard drive light blinking so I know its actually loading in the background. I can press ctrl-alt-backspace, and then ctrl-alt-delete to get the machine restarted. I have to choose "Recovery Mode" in Grub, then choose the "Resume" option. Doing it this way, X will load fine, but performance is terrible.. but it's all I got!

I can reproduce this every time I boot from cold, or restart the computer.
