Almost certainly it's the monitor not being able to sync to the output when he's outside of X. Checking his lspci above, he has an intel chipset. Looking at the module loaded list, he does indeed have intelfb loaded. Checking the log from 2.6.23-rc6 to -rc7 shows four patches (at least) against intelfb. Those people implicated are on the to: line now. Patches included below for your reading pleasure, but gmail will almost certainly hork them up; sorry about that. If I had to guess, the one from Krzysztof (third down) seems the most likely culprit, but I'll let others with the big brains decide. (Changesets pulled from mercurial, so they won't match up with git -- sorry. But there aren't that many patches from rc6 to rc7, so it shouldn't be hard to find these.)

The pixel clock (and thus both H and V sync) will be slower than requested, so if you set the minimum allowed the display may not sync. In case of really old CRT display it could theoretically damage it. I'm using it with PAL TV (using RGB input - SCART connector) and the bug prevented it from working at all (TV requirements are more strict and made the bug visible).
