Change to the directory /etc/X11, and do an ls. You'll notice that one of the files left there by the install is xorg.conf-vesa. All you have to do is copy that file to xorg.conf, though it's probably a good idea to make a backup of your existing file beforehand.
The long answer:
#mv xorg.conf xorg.conf-backup
#cp xorg.conf-vesa xorg.conf
And you're ready to startx. Though, you'll probably notice that in VESA mode, the graphics driver will not support a resolution higher than 1024x768.
