This would be true for, say, 2.6.21. For a pvops kernel such as 2.6.25, the
config setting is XEN_FBDEV_FRONTEND (for the domu), which typically is
builtin, not a module (as is also XEN_FRAMEBUFFER). Also note that in Xorg
7.3, with xorg-x11-drv-fbdev installed, and 'fbdev' as your video device in
your xorg.conf, it is actually /usr/bin/Xorg that opens the /dev/fb0 device,
which can be confirmed with 'lsof|grep /dev/fb'.

At one point, Ray did an 'apt-get -y install xorg', but that may have just
been experimentation.
I'm glad that you and Ray are putting your heads together on this. I was very
impressed how you researched that Xorg bug in your thread 'PV DomU VNC screen
black and Xorg error'.
