Seeking BSD friendly video card

[Dieter BSD]

Seeking a video card that is completely documented and is
fully supported (with source code) by the BSDs.

A gpu-less framebuffer is fine. (No videogaming)

PCIe
At least 2560x1440 (for 27" displays) (analog can be lower resolution)
 2560x1600 (30" displays) would be better
 4096x2560 (4K displays) would be even better
At least 24 bit color (more is better)
Work as console for firmware and OS. Must work with X11.

Bonus points for multiple heads (e.g. 2 digital + 1 analog)
Bonus points for each type of port supported (dvi, hdmi, displayport,
 vga, s-video, ...)

Bonus points for video decoder that is documented and fully supported by
 the BSDs.

Minor bonus points for a small, energy efficient gpu that is documented
 and fully supported by the BSDs.

Bonus points for not even needing a heatsink.
Major minus points for power hungry monsters with "jet engine" fans and
 extra power cables, double-wide, ...

Binary-only is unacceptable, must have source. (Can be BSDL, GPL, ...)

Bonus points for supporting sync-on-green.

Decent quality.

Full height is ok, doesn't need to be low profile.

Are there any other issues I should consider?
