Ok, here's something interesting. The screen is slightly unstable even in a text-mode console. The whole screen has a very slight shimmy going on. Keep in mind that just prior to installing Fedora, I had a Debian Sarge installed, and this did not occur, so there must being something going on with the way the Intel 810 driver is initializing the chipset. Any ideas?
