The only way to get screen content again is to reboot, which is possible either by pressing the ACPI-enabled power button or a remote SSH connection. Broken DPMS is suspected, although I have no way of confirming this. Purposely downgrading xserver-xorg-core and anything that depend on it, then pining it to that version, while keeping all the rest of the packages to Gutsy versions solves it, which suggests something related to X.org upgrade from 1.2 to 1.3 might be at play. Note: someone on #ltsp mentions a similar situation using xserver- xorg-video-amd, yet the exact same AMD driver doesn't exhibit this behavior when compiled and used with earlier X releases.
