Hello there....you are not alone. The screen freezing with the Dell XPS laptop happens with FC3.I now have gentoo with xorg 6.8 and kernel 2.6.10 on it right now, and sadly it exhibits the same problems as FC3. I loaded Fedora 2 and then Gentoo with xorg 6.7 and have not experienced the screen lockups. For me, the lockups seem to happen when I resize a terminal window, or open a new tab on browser or some small mouse movement. I too am at a loss.... I have not been able to catch what is causing this. My keyboard locks up, cnrt,alt,del cnrt,alt,bckspc cnrt, alt fn1.2.3.4 gets no response, but the big power button does. I do notice though, just before it freezes, the fan speed tends picks up in speed and sound. I am currently building a new kernel without apm/acpi..(pwr/green options). The ATI driver for gentoo wasnt that easy to install, but not up to 1920x1200. The ati drivers were easier to install on FC3, but sadly not up to 1920x1200 either. This laptop is great...but still miss the nvidia hardware :) If I am lucky and find the cause, it will be posted.
