Using the same fix in sidux (disable DRI in xorg.conf) also makes virtualbox stable - but the desktop is then prone to regular and frequent X rendering freezes. Switching to a VT and back again to X cures it, for a few minutes. In sidux - but not in Ubuntu in my experience - DRI must be enabled to have a stable desktop.
