On the Pegasos you can choose a different resolution in OF by defining the
words "screen-width" and "screen-height". For example:

  1024 to screen-width
  768 to screen-height

is missing when doing "pcictl pci0 list". :(

I could swear that worked in the past! Maybe a problem introduced by
switching pegasospci to gtpci...?
