output of dmesg

Using the latest git kernel tree (commit 91ed558e422465df7ea8f857785881a74528bb32), my CRT monitor loses the signal during the boot (right after the firmware request). The system seems to boot fine, though.

If I'm interpreting this right, the card switches to TV-out, but there is nothing connected to the card's TV-out connector:
