Hello Lisa and Alexey,

The support for selecting resolutions in xorg.conf was dropped for 1.3
and newer servers when support for randr 1.2 and dynamic resizing was
added (if you start the svn version of VBoxClient then you can resize
the guest by resizing the VirtualBox window now).  We should probably
make the guest remember the resolution used on shutdown next time it boots.

The workaround should be working.  I will investigate that.  The error
message in the log is harmless but should (will) also be got rid of.
