I'm pretty sure he's not.

Correct. The 'tty' bit is misleading. He's not getting any visible
text console when he hits ctrl-alt-f1 .. f6.

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.)

intel-agp: Fix i830 mask variable that changed with G33 support
The mask on i830 should be 0x70 always, later chips 0xF0 should be okay.

Subject: [PATCH] Intel FB pixel clock calculation fix
Intel framebuffer mis-calculated pixel clocks.
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).
