Fatal server error (X11)

[llista]

I have attempted to install FreeBSD6.2 and it all works fine right until attempt to "startx" then get this error message:

"Fatal Server Error:
No screen found"

then I check /var/log/xorg.0.log and I see one error

"(WW)xf86EnableIO: Failed to open /dev/io for extended I/O (EE) No devices found."

I have a Viewsonic VA22 monitor that works fine with Frenzy live CD based on FreeBSD6.1 so I dont really know what maybe wrong, Freesbie which is based on FreeBSD6.2 does not work neither, I get it fine right until startx then the monitor goes black.

Can you post your xorg.conf?
