Yes, you can reconfigure the framebuffer to any of the valid vofs for the
hardware that you have.

Three things we learned when we did this:
        1) Ensure the vof you are using is valid for the number of RMs you
have. Somewhere in the archives is a table of RMs and the depth/anti-aliasing/
multisample options that are supported for each size. This is a very important
chart that I always lose. We have 2 RM4s and were able to use the 1600x1200
mode.

        2) use the -mwidthxheight option of setmon to a standard size (e.g.,
1280x1064) for the monitor. This is how much you can see at one time, and has
to be something that the monitor will support.

        3) Desks Overview (ov) is very useful to move the window around on the
managed desktop.
