What I meant was the problem existed also in linux console, outside of X11.
However, it seems that at least the LCD display seems to work just fine with an
old ATI HD 2400 card & radeon driver (dpms works just fine):

08:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV610
video device [Radeon HD 2400 PRO]

I'll try the latest git version of kernel.org kernel as there has been some
updates to DVI connectors/connections code for radeon to my knowledge.
