Shouldn't be too hard.=20

 (a) It should be optional, either as a flag to the existing ioctl, or
     as a new ioctl.

 (b) CONS_GETINFO will need to be extended (or we need a new ioctl for
     the scrollback) to include information about how big the scrollback
     buffer is.

 (c) It might be worth providing a mechanism to let the application
     specify a rectangular window that it wants to grab from the buffer.

I'm a bit busy most of this week, but I might be able to do this toward
the end of the week.
