I finally had a chance to run quite stable X server on VT310-DP system. I changed my kernel configuration to use viadrmums driver instead of viadrm which was causing system reboot on X.org server initialization. However there is an issue that mouse pointer is not visible, it is working  though on blind clicking (there is an old bug report regarding that but it probably wasn’t look upon since the end of discussion almost four years ago Update: It seems that openchrome officially doesn’t support hardware cursor for integrated graphics in the chipset which is mentioned in the bug report, however it shouldn’t be the case for CN400 chipset, so possibly it is not related bug. Nevertheless, enabling SWCURSOR works as workaround). Thus I had a chance to test my  wine build a bit. Building wine instructions still holds true on my configuration for wine-devel package. Unfortunately, it appears not very usable, most applications just crush or start very slowly.  Nevertheless, I made a screenshot with notepad running (on wmaker wm).
