Is the main viewer of the monitor going to be a human? If so,
you don't require hard real time. There are plenty of real-time
video applications currently available for Linux that don't use
RTLinux.
If this is the case, I would strongly encourage using X, since it
is a lot more portable than SVGAlib, is more stable, can be debugged on
non-target machines, supports more devices, uses acceleration, etc.
