Did you install the emulators/virtualbox-ose-additions port? It should contain a video driver just for the virtualbox video card.

Both virtualbox and virtualbox-ose have a flag named guestadditions.
You should check this flag and when you install virtualbox, will also download and install virtualbox-ose-additions as dependencie as adamk said :)

VirtualBox 2.1.4 Guest Additions installation
Please install GNU make.
Please install the build and header files for your current Linux kernel.
The current kernel version is 8.0-RELEASE
Problems were found which would prevent the Guest Additions from installing.
Please correct these problems and try again.
