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?
It is a straight displayport connection.

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.
Does this work any better with the latest atom parser updates in drm-radeon-testing: http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=shortlog;h=refs/heads/drm-radeon-testing
I tried latest DDX and drm-2.6 radeon-testing. The screen still get no signal.
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.

The fix for KMS DP went in after rc6: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=9ce929078af868ce5f5b0b3537184dad642fba43
Created attachment 24878 [details] DP works
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?
thats a merge commit It affects radeon displayport f28cf33945cc112f8ee835512b7440905dc29ad2 43c33ed87d0f1b900a6a3014db556ecc7f4a989b 97b94ccb9aa1b82ed7a9a045d0ae5b32c99b84a0 are all radeon DP commits to fix it. I don't see any wireless stuff touched in that merge.
DP still not working with KMS.
