Default HP EliteBook 8440p (NVIDIA NVS 3100M) fails to restore screen after DPMS suspend

The display of my HP EliteBook 8440p with NVIDIA NVS 3100M graphics card
does not resume after dpms suspend or dpms off
by pressing keys or mouse movement.

This issue can easily be reproduced:
Code:
$ xset dpms force suspend
After this, pressing keys or moving the mouse does not restore the display.

The following error is logged in /var/log/Xorg.0.log:
Code:
(WW) Oct 23 00:50:42 NVIDIA(GPU-0): AUO (DFP-3): Failed to set DisplayPort power state
(WW) Oct 23 00:50:45 NVIDIA(GPU-0): AUO (DFP-3): Failed to set DisplayPort power state
(EE) Oct 23 00:50:45 NVIDIA(GPU-0): AUO (DFP-3): DisplayPort link training failed
Changing VTs (ctrl-alt-f1; ctrl-alt-f7) restores the display.

This issue does not occur when using version: 195.36.31 (the last version known to work)
It does occur when using todays latest version: 260.19.12

Currently the notebook is running
kernel-2.6.33.4
xorg-server-1.7.7

The problem description may be related to the following post, but I'm afraid:
It is NOT fixed in 260.19.12 (at least for the EliteBook)
