I am also affected by the flashes on the screen on my Dell Latitude Z600 since I upgraded to Lucid 64bit. Here are the details of my video card :

00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)

00:02.0 0300: 8086:2a42 (rev 07)
                       Subsystem: 1028:02c8
00:02.1 0380: 8086:2a43 (rev 07)
                       Subsystem: 1028:02c8

The workaround i915.powersave=0 fixes the issue.
