What kernel are you using?  You may be using an older drm without DP support.

I now use kernel 2.6.33-rc4, before it was 2.6.33-rc3.
[    0.000000] Linux version 2.6.33-rc4-desktop32 (root@desktop) (gcc version
4.4.3 20100108 (prerelease) (Ubuntu 4.4.2-9ubuntu3) ) #1 SMP Wed Jan 13
15:28:02 CET 2010
The screen gets a video signal until drm take over control form the bios and
switch to standby.
I was wrong to report non kms as operational. No sign of DP link in xrandr,
Xorg log or dmesg.

Are you using straight displayport or a displayport->DVI convertor?

The graphics card is a "Gainward Golden Sample 1024M 256Bit CRT DVI HDMI DP"
with a custom pcb layout. Maybe they wired the DP differently. When I'm using
Win7 + ATI driver, DP works as good as the DVI-D connection.

With the latest xf86-video-ati git version DP works if the screen was connected
at boot. When I connect it at runtime false modes are detected and I can't
enable the DP screen. KMS still refuses to detect it.

I don't understand how why 9ce929078af868ce5f5b0b3537184dad642fba43
affects the DP. I can see the changelog entry, but there does not seem
to be any code in it that actually did it. Also, the wireless changes in it
are strangely... unrelated. Can anyone point me to the function name
with the change?
