Had the same problem. My Acer TravelMate 662 laptop (Intel 855GM) refused to boot with Lucid. Adding boot option i915.modeset=1 fixed this problem.
Afterwards I was experiencing X crashes when playing videos with totem.
Installing the mainline kernel 2.6.33.3 provided by Ubuntu finally fixed all my problems, even the X crashes:
