(Get the code!)
nomodeset kernel option does nothing (at least on my kernel build), but radeon.modeset=0 does help. Worked an evening on the box with disabled modesetting now and didn't see a freeze/crash.
Only the mode detection is suboptimal... I have seen that in comparison to another Linux system I have on that box.. the image looked more crisp, less smearing on the LCD (that also covers the mode set using kernel modesetting). After manually fixing ip some tuned mode with slightly increased refresh rate (not 59.9 but rather 61 Hz or so) this is improved.
Main message: DIsabling kernel modesetting for RS690 _seems_ to be a good idea so far.
