Although applying http://bugs.freedesktop.org/attachment.cgi?id=22595 which I am assuming is the same as 157_check_null_modes.patch, does stop X segfaulting, apps that used to segfault X now just don't run at all. For example winecfg gives

X Error of failed request: XF86VidModeExtensionDisabled
  Major opcode of failed request: 134 (XFree86-VidModeExtension)
  Minor opcode of failed request: 6 (XF86VidModeGetAllModeLines)
  Serial number of failed request: 82
  Current serial number in output stream: 82

The problem seems to be that for some reason pScrn = xf86Screens[scrnIndex]; is returning an empty list of modes. Any ideas how to address this underlying issue?
